I, too, like the number 20, but not the number 11. In fact, 20 months has a nicer feel to it than 24. Get rid of those evil 6's... Appease the decimalists.

But what about the 11? Way too long. 10? Also too much of a change, I fear. 9? We don't like odd numbers any more. 8 then? Okay! A nice even number -- a week and a half would be 12 days, not 10.5 days. With 8 days, though, how do you arrange the work days and the weekend? Will people consent to switch from 5-2 to 6-2?

I say yes, and I'll tell you why: intercalary days. To make a 20-month perpetual calendar with 8-day weeks, each month is nominally 32 days. That leaves approximately 1.43 extra days per month. If they are tacked on to the end of the months and declared outside the weekly cycle (and thus non-work days), perpetuality is preserved and people end up working the same fraction over the month.

On Earth, 5 days out of 7 for 33.43 days results in 23.75 days of work.
On Mars, 6 days out of 8 (plus holidays) each month results in 24 days.
Please don't complain about the 2 hours!

Cons:
People aren't used to an 8-day week
People aren't used to a 20-month year
People aren't used to a 33-34 day month
People aren't used to intercalary days
People aren't used to perpetual calendars

Pros:
An 8-day week would be easy to use
A 20-month year would be easy to use
A 33-34 day month isn't much longer than a Gregorian month
Intercalary days provide a long weekend every month
Perpetual calendars are simple to use
It is not necessary to drop days out of the weekly cycle


As for the reason I call this the Pavonian Calendar, go look at the 20-month version of Bumps and Dips. . . | . . . . | . .
