Re: Date and time on Cindu: yearly update

OK, so after some offscreen back and forth, the new rule is this:

Since the position of the leap day moves around within the year, we
speak of "leap seasons".  Such leap seasons are evenly spaced,
comprising three within each 76-season span, centered on summer of the
year 700 (of the New Count).  Since 76 seasons is 19 years, there is
also a summer leap in 719, 738, 681, 662, etc.  In between, the gaps
run 25 seasons, then 26, then 25 seasons again. So the other leaps
around summer 700 are autumn 687, spring 694, autumn 706, and spring
713.

Under this rule there can never be a leap winter.

This has the same result as the earlier rule as far as which years are
leap; only the seasonal location of the leap day has changed.  But the
end result is that the leap days are more consistently spaced, with
only a one-quarter difference in the interleap gaps.
