Funny you say that since October started off as meaning the 8th month.

october is still a month "name", like decilis, not just "the 8th month"

It is a name now, but originates from an adjectival form of the latin number eight "octo"

About understanding, we're used to it but you can't trivially know whether 02/05/2026 is a Monday. Even remembering whether July has 30 or 31 days can be a chore. Irregular months also can have some small annoying effects since "in a month" is not always the same amount of days. There's even the 360 day calendar for that https://en.wikipedia.org/wiki/360-day_calendar Just one more in the long history of https://en.wi…

Year 2, month 5, day 2026?

You appreciate that no calendar can get around the mod 365 and leap year adjustments? That's baked into the Earth orbit around the Sun

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…

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!

Wrong approach. We should change our numbering system to base-12 instead.

A more sensible proposal than changing the calendar.

But consider base 12 has few advantages over base 6 but base6 greatly simplifies math since you only need to remember 24 entries for the commutative pair tables (multiplication)

Only because you’ve been trained your life to know the order. Plus the words don’t even sort.

They don't sort... in your language, or how you call them. So what?

Having dates (month names) that sort is great if you are a programmer.

Otherwise, so what indeed.

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 :)
