    Author makes a good point. "1700s" is both more intuitive and more concise than "18th century". The very first episode of Alex Trebeck's Jeopardy in 1984 illustrates how confusing this can be:

    https://www.youtube.com/watch?v=KDTxS9_CwZA

    The "Final Jeopardy" question simply asked on what date did the 20th century begin, and all three contestants got it wrong, leading to a 3-way tie.

      Logic is in short supply and off-by-one errors are everywhere. Most people don't care. I think it's more doable to learn to just live with that than to reprogram mankind.
      • zepolen 91 days ago
        That's what most people think and the world keeps trucking along.

        It's the rare people that don't who actually change the world.

    • jrockway 92 days ago
      On the other hand "1700s art" sounds like trash compared to "18th century art".
      • burkaman 92 days ago
        I think that's good, because it helps you realize that categorizing art by century is kind of arbitrary and meaningless, and if possible it would be more useful to say something like "neoclassical art from the 1700s". "18th century" isn't an artistic category, but it kind of sounds like it is if you just glance at it. "Art from the 1700s" is clearly just referring to a time period.

          no it won't lol, people will pay just as much through the new dating system as they would through the old.

      • bandyaboot 92 days ago
        If using “1700s”, I’d write it as “art of the 1700s”.
      • rz2k 92 days ago
        How about if you say "settecento"? Maybe it is a new confusion that they drop a thousand years, and maybe it would imply Italian art specifically.
        • lucb1e 92 days ago
          Just to make sure I understood this, that would be used as "17th settecento" to mean 1700s right?

          (This Xth century business always bothered and genuinely confused me to no end and everyone always dismissed my objections that it's a confusing thing to say. I'm a bit surprised, but also relieved, to see this thread exists. Yes, please, kill all off-by-one century business in favor of 1700s and 17th settecento or anything else you fancy, so long as it's 17-prefixed/-suffixed and not some off-by-anything-other-than-zero number)

          • animaomnium 92 days ago
            "settecento" can be read as "seven hundred" in Italian; gramps is proposing to use a more specific word as a tag for Italian art from the 1700s. Of course, 700 is not 1700, hence the "drop 1000 years". The prefix seventeen in Italian is "diciassette-" so perhaps "diciasettecento" would be more accurate for the 1700s. (settecento is shorter, though.)

            Hope this clarifies. Not to miss the forest for the trees, to reiterate, the main takeaway is that it may be better to define and use a specific tag to pinpoint a sequence of events in a given period (e.g. settecento) instead of gesturing with something as arbitrary and wide as a century (18th century art).

          • rz2k 92 days ago
            Think of it as the 700s, which is a weird way to refer to the 1700s, unless you are taking a cue from the common usage. That’s just how the periods are referenced by Italian art historians.
    • d0mine 91 days ago
      There is no "0" year, 1 is the 1st year, so 100th year is still the 1st century, therefore 2nd century starts in 101 and 20th in 1901.
      • notfed 91 days ago
        I find this decree frustrating. Someone could have just as easily said "the 'first' century starts at 1 BC" to account for this.
        • 38 91 days ago
          Or better yet just year 0, why not? Do we say the 80s start in 1981?
          • rdlw 91 days ago
            The concept of zero was not popularized in 500s Europe, when the system was devised.
    • runarberg 92 days ago
      In Icelandic the 1-based towards counting is used almost everywhere. People do indeed say: “The first decade of the 19th century” to refer to the 18-aughts, and the 90s is commonly referred to as “The tenth decade”. This is also done to age ranges, people in their 20s (or 21-30 more precisely) are said to be þrítugsaldur (in the thirty age). Even the hour is sometime counted towards (though this is more rare among young folks), “að ganga fimm” (or going 5) means 16:01-17:00.

      Speaking for my self, this doesn’t become any more intuitive the more you use this, people constantly confuse decades and get insulted by age ranges (and freaked out when suddenly the clock is “going five”). People are actually starting to refer to the 90s as nían (the nine) and the 20-aughts as tían (the ten). Thought I don’t think it will stick. When I want to be unambiguous and non-confusing I usually add the -og-eitthvað (and something) as a suffix to a year ending with zero, so the 20th century becomes nítjánhundruð-og-eitthvað, the 1990s, nítíu-og-eitthvað and a person in their 20s (including 20) becomes tuttugu-og-eitthvað.

          Also, when they switched things in 1582:

          https://www.britannica.com/story/ten-days-that-vanished-the-....

          > The most surreal part of implementing the new calendar came in October 1582, when 10 days were dropped from the calendar to bring the vernal equinox from March 11 back to March 21. The church had chosen October to avoid skipping any major Christian festivals.

        • pdonis 92 days ago
          The century in which the switch occurred (which was different in different countries) was shorter than the others. As were the decade, year, and month in which the switch occurred.
      • hgomersall 92 days ago
        No, the first century began Jan 1, 0000. Whether that year actually existed or not is irrelevant - we shouldn't change our counting system in the years 100, 200 etc.
        • Izkata 92 days ago
          The calendar goes from 1 BC to 1 AD, there is no year 0.
          • rcoveson 92 days ago
            There is no year zero according to first-order pedants. Second-order pedants know that there is a year zero in both the astronomical year numbering system and in ISO 8601, so whether or not there is a year zero depends on context.

            It's ultimately up to us to decide how to project our relatively young calendar system way back into the past before it was invented. Year zero makes everything nice. Be like astronomers and be like ISO. Choose year zero.

            • worstspotgain 92 days ago
              Yes but, is there such a thing as a zeroth-order pedant, someone not pedantic about year ordinality? As a first-order meta-pedant, this would be my claim.

              Moreover, I definitely find the ordinality of pedantry more interesting than the pedantry of ordinality.

              Or, just to add more fuel to the fire, we could use the Holocene/Human year numbering system to have a year zero and avoid any ambiguity between Gregorian and ISO dates.

            • jl6 92 days ago
              We are all defacto ISO adherents by virtue of our lives being so highly computer-mediated and standardized. I’m fully on board with stating that there absolutely was a year zero, and translating from legacy calendars where necessary.
            • hollerith 92 days ago
              I vote for a year zero and for using two's complement for representing years before zero (because it makes computing durations that span zero a little easier).
          • hgomersall 92 days ago
            What does that even mean? Do we allow for the distortion due to the shift from the Julian to Gregorian calendars, such that the nth year is 11 days earlier? Of course not, because that would be stupid. Instead, we accept that the start point was arbitrary and reference to our normal counting system rather than getting hung up about the precise number of days since some arbitrary epoch.
            • pdonis 92 days ago
              > What does that even mean?

              It means just what it says. In the common calendar, the year after 1 BC (or BCE in the new notation) was 1 AD (or CE in the new notation). There was no "January 1, 0000".

              • hgomersall 92 days ago
                As I said twice, whether that date actually existed or not is irrelevant.
                • pdonis 92 days ago
                  > whether that date actually existed or not is irrelevant.

                  No, it isn't, since you explicitly said to start the first century on the date that doesn't exist. What does that even mean?

                  • lupire 92 days ago
                    The first day of the 1st Century is Jan 1, 1 AD.

                    The point is that some days got skipped over the centuries, but there's no need to make the Centuries have weird boundaries.

                    • pdonis 92 days ago
                      > The first day of the 1st Century is Jan 1, 1 AD.

                      That's not what the poster I originally responded to is saying. He's saying the 1st Century should start on a nonexistent day.

                      • hgomersall 91 days ago
                        No, I'm saying we ignore when it actually started and instead use the normal rules of counting to decide what to call the respective centuries.
                      • antonvs 92 days ago
                        You can make this work by having the 1st century start on the last day of 1 BC. Think of it as an overlap if you like; it doesn't really matter.

                        That allows for consistent zero-indexed centuries. It doesn't have any other practical consequences that matter.

    • drivers99 92 days ago
      There are numerous common concise ways to write the 18th century, at the risk of needing the right context to be understood, including “C18th”, “18c.”, or even “XVIII” by itself.
      • anyfoo 92 days ago
        These are even more impractical, so I wonder what your point is? I can come up with an even shorter way to say 18th century, by using base26 for example, so let's denote it as "cR". What has been gained?

      Yea, but a rhetorical failure. This sounds terrible and far worse than alternatives.

      If we want a better system we'll need to either abandon the day or the Gregorian (Julian + drift) caliendar.

  • milliams 92 days ago
    It's easy, we should have simply started counting centuries from zero. Centuries should be zero-indexed, then everything works.

    We do the same with people's ages. For the entire initial year of your life you were zero years old. Likewise, from years 0-99, zero centuries had passed so we should call it the zeroth century!

    At least this is how I justify to my students that zero-indexing makes sense. Everyone's fought the x-century vs x-hundreds before so they welcome relief.

    Izzard had the right idea: https://youtu.be/uVMGPMu596Y?si=1aKZ2xRavJgOmgE8&t=643

    • mmmmmbop 92 days ago
      > We do the same with people's ages.

      No, we don't.

      When we refer to 'the first year of life', we mean the time from birth until you turn 1.

      Similarly, you'd say something like 'you're a child in the first decade of your life and slowly start to mature into a young adult by the end of the second decade', referring to 0-9 and 10-19, respectively.

      • Uehreka 92 days ago
        > No, we don't.

        But practically speaking we usually do. I always hear people refer to events in their life happening “when I was 26” and never “in the 27th year of my life”. Sure you could say the latter, but practically speaking people don’t (at least in English).

        • mjmahone17 92 days ago
          “Half one” is archaic English, and common German, for 12:30. Similarly “my 27th year” just sounds archaic to me: I wonder if you went through a bunch of 19th century writing if you’d see ages more often be “Xth year” vs “X-1 years old”.

          There may be something cultural that caused such a shift, like a change in how math or reading is taught (or even that it’s nearly universally taught, which changes how we think and speak because now a sizeable chunk of the population thinks in visually written words rather than sounds).

          • einherjae 92 days ago
            Isn’t “half one” used as a short form of “half past one” these days, I.e. 01:30? That has been a source of confusion for someone used to the Germanic way.
            • larusso 91 days ago
              I had this exact topic with an Irish coworker who lives in Germany and has issues to convey the right time. For me as a German „half one“ is half of one so 12:30. Same for „Dreiviertel eins“ -> „threequarter one“ being 12:45 and „Viertel eins“ -> „quarter one“ being 12:15. To be fair the logic behind this is also under constant confusion as some parts of Germany rather use „viertel vor“ or „viertel nach“ -> „quarter to“ „quarter after“ and have no understanding of the three quarter business.
          • Unbefleckt 92 days ago

              Do you say "half ten" to refer to 9:30? If so, you're using archaic English, yep!
        • mtlmtlmtlmtl 92 days ago
          That's not really indexing from 0 though. It's just rounding the amount of time you've lived down to the nearest year. You get the same number, but semantically you're saying roughly how old you are, not which year you're in. This becomes obvious when you talk to small children, who tend to insist on saying e.g "I'm 4 and a half". And talking about children in their first year, no one says they're 0. They say they're n days/weeks/months old.
      • jcelerier 92 days ago
        The first year of life is the year indexed with zero, just like the first centimeter/inch in a ruler is the centimeter/inch indexed with zero

        > When we refer to 'the first year of life', we mean the time from birth until you turn 1.

        Sure, but no one ever uses that phrasing after you turn one. Then it's just "when they were one", "when they were five", whatever.

        So sure, maybe we can continue to say "the 1st century", but for dates 100 and later, no more.

      • daynthelife 92 days ago
        My preference is semi-compatible with both conventions:

        First = 0 Second = 1 Toward = 2 Third = 3 …

        This way, the semantic meaning of the words “first” (prior to all others) and “second” (prior to all but one) are preserved, but we get sensical indexing as well.

        Can't say I've ever had to refer to someone's first year or first decade of their life, but sure I'd do that if it came up. Meanwhile, 0-indexed age comes up all the time.

      We don't 0-index people's ages. There are a million books about "baby's first year", while they're still 0 years old.
      • Terretta 92 days ago
        Except we do, as soon as we need the next digit.

        In "figure of speech", or conventual use, people start drinking in their 21st year, not their 22nd. In common parlance, they can vote in their 18th year, not their 19th.

        We talk of a child in their 10th year as being age 10. Might even be younger. Try asking a people if advice about a child in their "5th year of development" means you're dealing with a 5 year old. Most will say yes.

        So perhaps it's logical to count from zero when there's no digit in the magnitude place, because you haven't achieved a full unit till you reach the need for the unit. Arguably a baby at 9 months isn't in their first year as they've experienced zero years yet!

        Similarly "centuries" don't have a century digit until the 100s, which would make that the 1st century and just call time spans less than that "in the first hundred years" (same syllables anyway).

        It's unsatisfying, but solves the off by one errors, one of the two hardest problems in computer science along with caching and naming things.

          > In "figure of speech", or conventual use, people start drinking in their 21st year, not their 22nd. In common parlance, they can vote in their 18th year, not their 19th.

          That’s not the case, though. They can vote (and drink, in quite a few countries) when they are at least 18 years old, not when they are in their 18th year (who would even say that?)

          People are 18 years old (meaning that 18 years passed since their date of birth) on their 18th birthday. There is no need of shoehorning 0-based indexing or anything like that.

          > Most will say yes.

          Most people say something stupid if you ask tricky questions, I am not sure this is a very strong argument. Have you seriously heard anybody talking about a child’s “5th year of development”, except maybe a paediatrician? We do talk about things like “3rd year of school” or “2nd year of college”, but with the expected (1-indexed) meaning.

          > So perhaps it's logical to count from zero when there's no digit in the magnitude place, because you haven't achieved a full unit till you reach the need for the unit. Arguably a baby at 9 months isn't in their first year as they've experienced zero years yet!

          It’s really not. To have experienced a full year, you need a year to have passed, which therefore has to be the first. I think that’s a cardinal versus ordinal confusion. The first year after an event is between the event itself and its first anniversary. I am not aware of any context in which this is not true, but obviously if you have examples I am happy to learn.

          > It's unsatisfying, but solves the off by one errors, one of the two hardest problems in computer science along with caching and naming things.

          Right. I know it is difficult to admit for some of us, but we are not computers and we do not work like computers (besides the fact that computers work just fine with 1-indexing). Some people would like it very much if we counted from 0, but that is not the case. It is more productive to understand how it works and why (and again cardinals and ordinals) than wishing it were different.

          • Terretta 92 days ago
            > who would even say that?

            Writers.

            And yes, cardinal versus ordinal is my point. The farther from the origin, the less people are likely to want them different.

        • kdmccormick 92 days ago
          What? No. When you are 0, it is your first year. When you are 21, you have begun your 22nd year. In the US you are legal to drink in your 22nd year of life.

          You are correct that nobody says "22nd year" in this context, but nobody says "21st year" either. The former is awkward but the latter is just incorrect.

            On the contrary, enough people say it, it's a quora question:

            https://www.quora.com/What-does-it-mean-to-be-in-your-twenty...

            Authors love phrases like this. Which, in turn, comes from another ordinal/cardinal confusion stemming back to common law:

            "A person who has completed the eighteenth year of age has reached majority; below this age, a person is a minor."

              It's just not true. You've completed being 17 years old on your 18th birthday, when you enter your 19th year and can count 18 years under your belt.

              Consider a newborn. As soon as they're squeezed out they are in their first year of life. That continues until the first anniversary of their decanting, at which point they are one year old and enter their second year of life.

              There is nobody, nobody, who refers to a baby as being in their zeroth year of life. Nor would they refer to a one-year-old as still being in their first year of life as if they failed a grade and are being held back.

              The pattern continues for other countable things. Breakfast is not widely considered the zeroth meal of the day. Neil Armstrong has never been considered the zeroth man on the moon nor is Buzz Aldrin the first. The gold medal in the Olympics is not awarded for coming in zeroth place.

                No one's saying it's true! All that's being claimed is that writers will often use phrases like "became an adult in their 18th year" or "was legally allowed to drink in their 21st year".

                It's completely incorrect, but some people use it that way, and ultimately everyone understands what they actually mean.

              The top response in your Quora link is that your 21st year "means you’re 20. You have had your 20th birthday, but not yet your 21st." That is the conventional definition.

              People commonly make the mistake of thinking otherwise, but that's all it is. A mistake.

          I don't think it is a mistake for Lua. The convention to zero-index arrays is not sacrosanct, it's just the way older languages did it (due to implementation details) and thus how people continue to do it. But it's very counter-intuitive, and I think it's fair game for new languages to challenge assumptions that we hold because we're used to past languages.
          • weinzierl 91 days ago
            > "it's just the way older languages did"

            It's a C family (predecessors and descendants) idiosyncrasy that very unfortunately got out of hand. Most other old languages had either 1-based indexing or were agnostic. Most notably FORTRAN, which is the language for numerical calculations is 1-based.

            The seminal book Numerical Recipies was first published as 1- based for FORTRAN and Pascal and they only latter added a 0-based version for C.

            Personally, coming from Pascal, I think the agnostic way is best. It is not only about 0-based or 1-based but that the type system encodes and verifies the valid range of index values, e.g. in Pascal you define an array like this:

                temperature = array [ -35 .. 60 ] of real;
            
            You will get an immediate compule-time error if you use

               temperature[61];
            
            At least with Turbo Pascal you could chose if you wanted run-time checks as well.

            I have a hard time wrapping my head around the fact that this feature is pretty much absent from any practically used language except ADA.

          • antonvs 92 days ago
            It's not counter-intuitive at all, it only seems that way because people are now used to languages with zero-based indexing. That's almost entirely because of the C language, which used pointer offset arithmetic with its arrays.

            Outside of that machine context, where an array is a contiguous block of RAM that can be indexed with memory pointers, there's no particular reason to do offset indexing. 1-based works just fine - "first element, second element" - works just fine and is perfectly intuitive.

            Different types of indexing can make sense in different situations. Some languages even allow that. In Ada, for example, arrays can start at whatever index you define.

      Here we say something like the "ninteen-hundred-era" for the 1900s, "ninteen-hundred-ten-era", for 1910s, "ninteen-hundred-twenty-era", etc. In writing 1900-era, 1910-era, 1920-era.

    A lot of this runaround is happening because people get hung up on the fact that the "AD" era began as AD 1. But that year is not magic--it didn't even correlate with the year of Jesus's birth or death. So let's just start the AD era a year before, and call that year "AD 0". It can even overlap with BC 1. BC 1 is the same as AD 0. Fine, we can handle that, right? Then the 00s are [0, 100), 100s are [100, 200), etc. Zero problem, and we can start calling them the 1700s etc., guilt free.

      Things like "17th century", "1600s", or "1990s" are rarely exact dates, and almost always fuzzy. It really doesn't matter what the exact start and end day is. If you need exact dates then use exact dates.

        Exactly. Historians often talk about things like "the long 18th century" running from 1688 (Britian's "Glorious Revolution") to 1815 (the defeat of Napoleon) because it makes sense culturally to have periods that don't exactly fit 100-year chunks.

          I thought the article was going to argue against chunking ideas into centuries because it's an arbitrary, artificial construct superimposed on fluid human culture. I could get behind that, generally, while acknowledging that many academic pursuits need arbitrary bins other people understand for context. I did not expect to see arguments for stamping out the ambiguities in labellibg these arbitrary time chunks. Nerdy pub trivia aside, I don't see the utility of instantly recalling the absolute timeline of the American revotion in relation to the enlightenment. The 'why's— the relationships among the ideas— hold the answers. The 'when's just help with context. To my eye, the century count labels suit their purpose for colloquial usage and the precise years work fine for more specific things. Not everything has to be good at everything to be useful enough for something.
    • card_zero 92 days ago
      This reminds me that centuries such as "the third century BC" are even harder to translate into date ranges. That one's 201 BC to 300 BC, inclusive, backward. Or you might see "the last quarter of the second millennium BC", which means minus 2000 to about minus 1750. [Edit: no it doesn't.]

      In fact archeologists have adapted to writing "CE" and "BCE" these days, but despite that flexibility I've never seen somebody write a date range like "the 1200s BCE". But they should.

      • arp242 92 days ago
        Some people have proposed resetting year 1 to 10,000 years earlier. The current year would be 12024. This way you can have pretty much all of recoded human history in positive dates, while still remaining mostly compatible with the current system. It would certainly be convenient, but I don't expect significant uptick any time soon.

        For earlier dates "n years ago" is usually easier, e.g. "The first humans migrated to Australia approximately 50,000 years ago".

      • localhost8000 92 days ago
        > you might see "the last quarter of the second millennium BC", which means minus 2000 to about minus 1750.

        From comparing some online answers (see links), I'd conclude that even though the numbers are ordered backward, "first"/"last"/"early"/"late" would more commonly be understood to reference the years' relative position in a timeline. That is, "2000 to about minus 1750" would be the first quarter of the second millennium BC.

    > This leaves ambiguous how to refer to decades like 1800-1809.

    There is the apostrophe convention for decades. You can refer to the decade of 1800–1809 as "the '00s" when the century is clear from the context. (The Chicago Manual of Style allows it: https://english.stackexchange.com/a/299512.) If you wanted to upset people, you could try adding the century back: "the 18'00s". :-)

    There is also the convention of replacing parts of a date with "X" characters or an em dash ("—") or an ellipses ("...") in fiction, like "in the year 180X". It is less neat but unambiguous about the range when it's one "X" for a digit. (https://tvtropes.org/pmwiki/pmwiki.php/Main/YearX has an interesting collection of examples. A few give you the century, decade, and year and omit the millennium.)

    Edit: It turns out the Library of Congress has adopted a date format based on ISO 8601 with "X" characters for unspecified digits: https://www.loc.gov/standards/datetime/.

        Of course, they are important, but so are many other things - and speaking e.g. from a European POV, a lot of other events are simply much more salient and commonplace - and the same is probably even more true for other continents (would a random reasonably educated American or European person know when the Meiji restauration happened or when Latin America became independent?). You can't expect everyone to have memorised all the important dates.
        • mixmastamyk 92 days ago
          America was a backwater at the time and therefore the best place to experiment with European enlightenment ideals. Which it did, and was a direct factor in the French Revolution. I also learned about numerous revolutions in Latin America from Mexico to Bolivar to San Martin over the early 1800s.

          The events that directly affect the modern world should be covered in school. I’d say revolutions that created large modern states would be among them.

          • Tainnor 92 days ago
            Of course, we learn about the American Revolution in schools, but people aren't going to remember every date they were taught in schools. The founding of Rome or the Punic Wars are also hugely important for today's world, but not everyone can place them.

            The reason most US Americans probably can place the American Revolution is because I assume it's so often commememorated there. In Germany, people would be much more likely to remember the years 1933, 1949 and 1989, because of how often they're referenced.

      Funny, when you say "20s" I think of the 1920s (aka the "Roaring 20s" here in the US). I wonder if it's an age thing (I'm in my 40s), or perhaps a cultural or regional thing.

      The 30s as 1930s seems pretty solid to me: US Great Depression, start of WWII, not to mention many of the smaller conflicts that led up to it.

    I like the German Nullerjahre (roughly, the nil years). Naught years or twenty-naughts works pretty well too imho.

    Meh. I acknowledge that the author can split a hair with their bare hand while blindfolded. But to convince everyone else they would have to lift the rest of the world to their level of pedantry.

    Thankfully, most of us quit writing centuries in Roman numerals, it's about time we quit centuries as well :) Sadly, however, the regnal numbers continue to persist
  • transfire 92 days ago
    We just need a new word to mean “0-indexed count of centuries”.

    Not sure what a good word for this would be, but maybe just use what we already say — “hundreds”.

    So, in the late 17th hundreds, …

  • kingkawn 92 days ago
    This is pretty easy to understand if you try whatsoever
  • Grom_PE 92 days ago
    I agree. Another good point to get rid of counting centuries would be that in some languages (Russian) centuries are written in Roman numerals. It's annoying having to pause and think of conversion.
  • wwilim 92 days ago
    1800-1899 is the eighteen-hundreds, 1800-1809 is the eighteen-noughties. Easy.
  • redhippo 92 days ago
    I thought the exact same thing... when I was eight. Then I just learned the mental gymnastics of hearing, say, "20th century" and associating it with "1900" at got along with it. Really, it's a bit dated, but if people can function with miles and furlongs, they can handle centuries...
    • kelnos 92 days ago
      It's funny, I'm in my 40s and my brain still pauses longer than I'd expect is necessary to do that conversion. I think for 21st or 20th century I'm fine (since I've lived in both of them), but anything prior and it takes me a beat to figure out which date range it is.
  • renewiltord 92 days ago
    I'm going to count centuries but just call it the 0th century until 100 CE. I anticipate no problems.
  • samatman 92 days ago
    Technically, decades and centuries start in a January with one or two zeros at the end, respectively. So the 1700s and the 18th century are exactly the same interval of time.

    ISO 8601-2:

    > Decade: A string consisting of three digits represents a decade, for example “the 1960s”. It is the ten-year time interval of those years where the three specified digits are the first three digits of the year.

    > Century: Two digits may be used to indicate the century which is the hundred year time interval consisting of years beginning with those two digits.

  • James_K 92 days ago
    Another ambiguity, though perhaps less important, is that "2000s" could refer to 2000-2999.
    • kelnos 92 days ago
      Not "another"; the article addresses this, and admits to not having a good solution, aside from just writing out the actual dates as you did.
    • lucb1e 92 days ago
      Took me a while to understand what's ambiguous about that. For anyone else, what they're saying is that this often (typically, I guess) refers to 2000-2099 and not the other 900 years.
    • MarkLowenstein 92 days ago
      Could make the convention to say "the twenty hundreds" when referring to [2000, 2100), and "the two thousands" for [2000, 3000).
      • kelnos 92 days ago
        I actually really like that!

        But then how about [2000, 2010)? During the current time period, I expect people are more likely to refer to the decade rather than the century or millennium.

    In terms of music this is true.

  • Isamu 92 days ago
    Well yeah, most of the time if I want to be understood I will say “the 1700s” because it is straightforward to connect with familiar dates.

    We still say “20th century” though because that’s idiomatic.

    • macintux 92 days ago

    > There’s no good way to refer to 2000-2009, sorry.

    The author is wrong here. The correct way (at least in spoken West Coast American English) is the Twenty-aughts. There is even a Wikipedia page dedicated to the term: https://en.wikipedia.org/wiki/Aughts If you want to be fancy you could spell it like the 20-aughts. I suppose there is no spelling it with only digits+s though, which maybe what the author was looking for.

    • kelnos 92 days ago
      I'm not sure why, but every time I hear someone use that term, I cringe. The word just feels... off... to me for some reason. Like it's an abomination.

      small issues are easy to solve!

      I think it isn't as sexy/interesting as what I thought the article was going to be about (about a different way of talking about our history, in eras maybe vs centuries or something).

      this strikes me as kind of like a small PR to our language that makes an incremental improvement to a clearly confusing thing. Should be easy to merge :)

      • kergonath 92 days ago
        > Should be easy to merge :)

        Famous last words.

        Seriously, though, we should have learnt at this point: we cannot solve social issues with technology. Everybody is working on a different tree, and social dynamics that govern the spread of idioms and from which fork you cherry-pick or merge is much more complex than what git is designed to handle.

        No, not easy. You want to change ao social convention? That is not easy.

        Even changing all the places it got encoded into software probably wouldn't be easy.
