Can anyone explain the divisibility thing more clearly to me, please? Given how easy the metric system is, what are the situations where base 12 would have a practical advantage?

Whereas, if you have something that's 1 metre long (1000mm), which you need to cut into three pieces, you mark and cut at 333mm and 667mm. Which are both 1/3mm off. Of course, if you want to cut it into five pieces, the problem's reversed. ![]() |

Of course, the divisibility by 12 only applies to lengths. For weights (at the kg level), you have pounds and ounces with 16 ounces to the pound. Only divisible by 2, 4 and 8.
For liquid measures it's the same in the US (16 fl.oz. to the pint) but different in the UK (20 fl.oz. to the pint.) (Luckily the difference between the US fl.oz. and the imperial fl.oz. is negligible for domestic use) The hundredweight is fun: 112 pounds, or 8 stone. (14 pounds to the stone, of course. Great for divisibility by 7. I don't know why the US doesn't use it.) 16 ounces to the pound 14 pounds to the stone 20 stone to the hundredweight 8 stone to the ton. More divisibility than one can shake a rod at. |

And people wonder why I like metric.

What dates are 12/10/2023 and 02/03/2023?
This is why the world should go computer date format 2023-07-04. Everyone would know what that date is and it would sort properly. |

The sorting is nice, but in everyday life I just routinely use 4 Jul 2023. Clear to everybody.

Being a developper on ms-sql databases i Denmark, I hate dates. I have to show the dates on the screen in the format dd:mm:yy. Så the date 12.03.23 is the 12 of march 2023. But its saved in the database as '2023-03-12 09:30:51.500'. (yyyy:mm:dd and the time). And lets not forget the timezones. Is it +1, -1?, or what happens during the daylight saving time. When was data entered with a timestamp 02:30:000? Relatively important in healthcare applications that I am coding. But i haven't got a solution :-)

In filenames or things like that, I use 2023-02-01 for sorting. But I prefer to use 'Feb 1 2023' if I can get away with it.

If I was going with an all-numbers format then I'd use YYYY-MM-DD. A long time ago I wrote a program in BASIC and used the "YYYY-MM-DD" to make sorting easy. Writing the date in "MM-DD-YYYY" format would necessitate a lot of program lines (with many subroutines) to get it to sort properly. |

I remember reading/hearing somewhere that a base of 6 might be a viable alternative to 10 or 12 since: (1) it has the above factors, and (2) it doesn't involve the creation of two new symbols as would be need with base 12. |
