The bug is a small one: it checks the month in a leap year to be equal to 3 (March) instead of greater or equal (March or later). As a result the first day of the month of the months after March are not shifted as it should have been. Here is the diff for the change. Line numbers may differ, but PScal can also be corrected using an editor of your choice: change the "eq" to a "ge" in the right place. ----------- text of diff follows ----------------- *** /tmp/,RCSt1007388 Mon Apr 18 13:28:51 1988 --- /tmp/,RCSt2007388 Mon Apr 18 13:28:51 1988 *************** *** 183,189 **** /off exch def 1 1 month 1 sub { days_month exch 1 sub get ! month 3 eq isleap and firsttime and { --- 183,189 ---- /off exch def 1 1 month 1 sub { days_month exch 1 sub get ! month 3 ge isleap and firsttime and { ----------- End of diff text --------------------- Good Luck, Ze'ev. ---- Ze'ev Shtadler.

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.... > Here is the diff for the change.

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).
