Bug report for /usr/bin/calendar
SUMMARY: calendar does not match "Thu+1" or "Mon+1" in some months.
With one exception, it looks like calendar file dates such as "Thu+1"
and "Mon+1" are failing to match in two cases: (1) the 7th of Jan-Nov,
and (2) December.
DETAILS/EXAMPLES:
FreeBSD crystal 9.0-RELEASE FreeBSD 9.0-RELEASE #0: Tue Jan 3 07:46:30 UTC 2012 root@farrell.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC amd64
The bug occurs whether or not the command line options below are used.
I first noticed it today (a Wednesday) because a Thu+1 event tomorrow was
not in calendar's output.
Example 1: Thu+1
~/.calendar/calendar:
Thu+1 foo (that's "Thu+1\tfoo\n" in C)
foreach i ( 1 2 3 4 5 6 7 8 9 10 11 12 )
&calendar -t 1.$i.2011 -W 9
&end
