Re: Date and time on Cindu

OK, since there's some interest, I'll keep sending at least some of
this stuff to the list, but duly marked as OT.

For calculation purposes, I plan to represent a Cindu date as a list
of four integers: year (new count), month (1-16), week (1-4), day
(1-7).

Cinjurak is represented as day 8 of week 2.

A leap day before day 1 is represented as day 0 of week 1.

A leap day midmonth is represented as day 0 of week 3.

This keeps the dates in the proper order, including the blank days,
while maintaining the property that the day number within the month is
7*(week-1) + weekday.

I can easily convert a date in a non-leap year to an absolute day
count (that includes leap days in prior years); just working out the
easiest way to determine if there's a leap day in the year under
consideration prior to the date under consideration.
