=================================================
(C) 2000-12-27, Magnus Bodin <magnus@bodin.org>


Christmas day (25th of December) occurs on sundays when the year starts
with a saturday on an ordinary year or starts with friday on a leapyear.
The distribution is shown relative to the gregorian epoch (400 years) which
is the cycle that our calendar revolves with. After 400 years everythin repeats
again. (See also yeartypes)
