The Duodecimal Bulletin, Vol. 55, No. 1, Year 1209 [pdf] (dozenal.org)

1209 is 2025, to answer the first question I had.

12 is, in many ways, a better base than 10 (divisible by 2,3,4 and 6 vs 2 and 5). And it was used in many British/Imperial units. But the chance of the world moving existing systems from base 10 to base 12 is surely so close to 0 as makes no difference?

I'm more of a seximal man myself: https://www.seximal.net/

What's the deal with that upside-down 2 on the title page? I first thought it would be one of the two additional digits, but those are visible on the "clock face" circle on the first page and look nothing like it.

(or are upside-down digits their way to mark icky base-10 numbers if they have to write them?)

Edit: ah, they explain it on page 23.

On page ↋: "Did you ever wonder just what the number system would be like if man had been created with 12 fingers?" (and an illustration).

With the advent of modern AI tools, this question has never been more important.

The upside down 2 and 3 to represent 10 and 11 look really dumb. Feels like a lazy solution rather then extending the character set with something interesting or unique.

This is for people who think Esperanto is too successful. I was amazed to see pictures of women in there, since there are none among the directors or writers...

I bet that annual meeting they held in that wee room back in 1983 was riveting.

I feel obliged to drop the School House Rock video/song “Little Twelve Toes” here. It’s the earliest exposure to alternative counting systems for me.

And to think, people are concerned that humans will struggle to find meaning in life after the AI utopia obviates the need for work.

The best base, and I think everyone can agree, has and always will be 10, regardless of one's radix persuasion.

So…if we had already been using a base-12 counting system when metric came along, we would have the best of both worlds.

The dozenal movement seems based (no pun intended) mostly on opposition to the metric system.

The article on page 38 is really funny to anyone not in the US:

    Fahrenheit temperature usually ranges from about 0° (cold) to about 100°
    (hot). On the other hand, those who use the awkward Celsius scale usually range from
    about 18° to about 38°! Interesting.

(18-22 °C is room temperature, 38 °C = 100 °F = hot summer day. 0 °F is way below freezing, a lot colder than it gets in most places!).

And apparently only the metric system was imposed by tyrannical governments. Maybe someone could ask the people in metric countries today if they would like to go back to the "natural" measurements that were in use before that happened? And maybe also switch to counting everything in dozen and gross at the same time.

Even if that really were objectively a better system, I think few would make that change if it wasn't forced on them.
