When it comes to the number of months in the year, 10 is an entirely arbitrary number because, unlike the metric system, there's no opportunity to leverage the convenient zero-shifting property of a base-10 numeral system (the concept of "kilomonths" and "megamonths" is incoherent as a unit of measure given that the number of days in a year is not divisible by 10). Might as well just smooth out the current 12 months (12 being a more highly composite number than 10) to 30 days each and then save the leftover days for a worldwide party outside of time.

I don't completely agree; when using a year as base unit, it makes somewhat sense both directions. Deka- and hectoyears are equal to common decades and centuries, and megayears would be relevant for geology and astronomy etc. In other direction deci- and centiyears could be sensible, equaling a decimal "month" and "week" respectively.

Playing devils advocate here, the problem with this proposal is that it didn't go far enough with its decimalization. A "better" (more decimal) approach would be to divide year to 100 "weeks" (10 "months" with 10 "weeks" each), and have each "week" vary in number of days. This would open up to fun ways to notate it, for example now (2023-12-17T21:03:31Z) could be "2023.95/2.87744Z", i.e. "week" 95 (or month 9 week 5) of 2023, day 2 of the "week", and 877.44 millidays ("minutes") since midnight. It's only slight abuse of decimal notation :)

you're right of course, but man I wish we had megamonths, the name is great.

you're describing the French Republican calendar btw. I blame Christianity for the travesty of stopping it's adoption. https://en.wikipedia.org/wiki/French_Republican_calendar?wpr...

Ya, those pesky Christians. If only Robespierre wasn't so reluctant to use the guillotine. Too few Vendees I tell you!
