Let's stop counting centuries

The article discusses the convention of counting centuries and suggests using "the 1700s" instead of "the 18th century" to avoid confusion. It highlights how our normal interaction with dates differs from counted centuries and proposes a simple solution to make it easier to understand. The author also addresses the ambiguity between decades and centuries, proposing a convention where trailing zeros indicate ranges. Additionally, the article touches on language evolution and the importance of adapting conventions for clarity. It concludes by emphasizing the need for language to evolve easily and suggests practical ways to refer to specific time periods. The piece also includes sections on travel advice, survey results, things that may not work well for most people, and various short topics like jokes and observations.

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.

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.

Another example of confusing numeric systems emerges from 12-hour clocks. For many people, asking them to specify which one is 12AM and which one is 12PM is likely to cause confusion. This confusion is immediately cleared up if you just adopt a 24-hour clock. This is a hill I'm willing to die on.

I thought this article was railing against the lumping together of entire spans of hundreds of years as being alike (ie, we lump together 1901 and 1999 under the name ”the 1900s” despite their sharing only numerical similarity), and was interested until I learned the author’s real, much less interesting intention

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.

I do tend to say "the XX00s", since it's almost always significantly clearer than "the (XX+1)th century".

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

This isn't really an argument against the new convention, since even in the old convention there was no convenient way of doing so.

People mostly just say "the early 2000s" or explicitly reference a range of years. Very occasionally you'll hear "the aughts".

> 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/.

I got a fight recently with a philosophy teacher about that, I changed the dates like the op to be more clear on my writing, she took it so seriously, it was a big fight about clarity vs. tradition but really superficial and mean on both sides. Now I wish to be* more articulate and have a good debate. I wrote it in my way on the final exam and approved, she had to deal with it I guess.

* Sorry, I don't know how to write that in past, like haber sido in Spanish, my main language.

This was confusing to me as a kid, especially as we entered the 21st. I also still remember learning about the Dutch golden age in elementary school, but can't remember if it was the 1600s or 16th century.

I'm running into a similar issue recently. Turns out that many people saying they are '7 months pregnant' actually mean they are in the 7th month, which starts after 26 weeks (6 months!)

I’ve just taken to writing things like: 201X or 20XX. This is non-standard but I don’t care anymore, referencing events from 20 years ago is just too annoying otherwise.

In spoken conversation, I dunno, it doesn’t seem to come up all that often. And you can always just say “20 years ago” because conversations don’t stick around like writing, so the dates can be relative.

If I lived much longer than 100 years I might care more about the precision of such language. However, as it stands, I know what people mean when they say "remember the early 2000s". I know that doesn't mean the 2250s for example - a reasonable characterization for someone living in 3102 perhaps.

I have heard people use "the aughts" to refer to this time range [1]. I guess if I was trying to be specific about which century one could say "the two thousand aughts" or "the eighteen hundred aughts". But I think in that context i'd be more likely to say "in the first decade of the 1800s"

The issue, of course, is that “counted centuries” are off by one from how we normally interact with dates—the 13th century starts in AD 1201.

The author misses. The author would like to skip some significant interpretive steps, chiefly when our dynamically typed language uses number words or characters in different contexts. Suggested reading is about the differences between and use cases of nominal, ordinal, cardinal, interval and ratio.

The article does not really resolve the ambiguity with 2000s which usually means 2000-2009, not 2000-2099.

That said, in Finnish language people never count centuries. It's always "2000-luku" and "1900-luku", not 21th and 20th.

>The issue, of course, is that “counted centuries” are off by one from how we normally interact with dates—the 13th century starts in AD 1201. There’s a simple solution. Avoid saying “the 18th century”, and say “the 1700s” instead. Besides being easier to understand, it’s also slightly shorter.

The kind of person who cares and reads about "the Xth century" can also trivially understand the date range involved.

The kind of person who can't tell 18th century is the 1700s and 21st century is 2000s, it would make them little good to read history, unless they get the basics of counting, calendars, and so on down.

By @arp242 - 6 months
I've always written it like "1900s", and always considered "20th century" to be confusing. Having to mentally do c-- or c++ is confusing and annoying.

I deal with the "2000s-problem" by using "00s" to refer to the decade, which everyone seems to understand. Sometimes I also use "21st century"; I agree with the author that it's okay in that case, because no one is confused by it. For historical 00s I'd probably use "first decade of the 1700s" or something along those lines. But I'm not a historian and this hasn't really come up.

By @samatman - 6 months
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.

    - 1800s: The Imperial Century
    - 1900s: The Century of Oil
    - 2000s: The Current Century (to be renamed in 2100)

You need to count from 0.

1 BC should be renamed year 0. Then the years 0-99 are the 0th century, the years 1900-1999 are the 19th century, etc.

To avoid confusion between new style and old style centuries, create a new word, "centan", meaning "100 years" and use cardinal instead of ordinal numbers, for conciseness. Then the years 1900-1999 are the 19-centan.

I understand the difficulty, but I don't think it is too terrible for us to get used to it and we aren't gonna change the past 500 years of literature that already did this.

Also, it's ironic for a bunch of people who literally count arrays from zero to be complaining about this... :-P

By @croemer - 6 months
I think this is incorrect. Don't centuries start with the 00? In that case the first year of a century is 0, and the 76th year would be 75, not 76 as the author writes:

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.

We should also stop talking about decades for the purposes of periodization. For example, the “‘80s” arguably ran from the election of Reagan in 1980 to the appointment of Bush W. by the supreme court in 2000. Politically, economically, and culturally, the “90’s” were an elaboration on the “80’s” (e.g. the deregulation and market reforms of Clintonism just being a whitewashed expansion of what Reagan did).

There is no such thing as a word for "1700s" in most European languages.

Also in English it sounds weird, as you have to pronounce it "seventeen-hundreds" whereas the correct pronunciation is "one-thousand-seven-hundred". So 1700s is unsuitable for formal writing or speaking and doesn't map naturally to most languages of Western civilization.

But yeah, I guess the author finds it hard to subtract 1 in his mind :) I could go off about the typical US-centric arrogance that I see on this site, but I think it's already pretty funny as it is.
