Bug ID: 288406
Summary: calendar(1) with -A 0 wrongly getting set to 1 in some
conditions
Product: Base System
Version: Unspecified
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bin
Assignee: [email protected]

Normally, using calendar(1) with `-A 0` should give only today's calendar
reminders, not the next day's. However, in certain conditions, it seems to get
overridden:
$ date +"%a %Y-%m-%d"
Wed 2025-07-23
$ calendar -A 0 -f /usr/share/calendar/calendar.freebsd | cut -f1 | uniq
Jul 23
Jul 24
This appears to be caused by day.c:settimes() which correctly receives an
`after` value of 0, but then overrides that in the first `if` clause, setting
it to 1:
/* Friday displays Monday's events */
if (after == 0 && before == 0 && friday != -1)
after = tp.tm_wday == friday ? 3 : 1;
inserting debug probes before/after this statement, the `after` value gets set
to 1 instead of the 0 from the command-line. I'm not sure how that logic is
*supposed* to work, but I'm almost certain it's wrong. Either it should be `:
0` not `: 1`. or the check should be `after == 1` (my vote for most-likely) or
`after > 0` instead of `after == 0`.
