Weird... I didn't notice any problem either, and after several different
people mentioned it, I figured I must be even more twisted than I thought.
But then I read on....

I looked at the diff, looked at my copy of pscal, looked at the diff,
scratched my head, looked at my copy of pscal, looked at the diff,
scratched my head... it appears that the reason most recipients of the
new calendar program didn't notice the problem is because it doesn't
exist in their version.  Perhaps two versions made it out on the net;
mine certainly has no test for "month 3 ge", or for "month 3 eq" for
that matter; only for "month 2 eq".

Maybe the people with the bad calendars are using the old crufty pscal?
Mine is marked "Copyright (C) 1987 by Pipeline Associates, Inc.", and
was posted around the beginning of April (it has since expired and I
have since modified my copy, so I can't dredge up the posting date).
