On OpenBSD-current amd64 last snapshot, when using calendar -B flag, I get a date which is due in 3 days when I want to show events in the past 33 days. Using an other range of days doesn't work, it has to be 33. Past events are correctly shown though.
This is reproducible on 6.4 release as well. How to reproduce: solene@t480 ~ $ cat .calendar/calendar 12 January bug solene@t480 ~ $ calendar -B 33 -t 20190109 Jan 12 bug solene@t480 ~ $ calendar -B 50 -t 20190109 solene@t480 ~ $ calendar -B 32 -t 20190109 solene@t480 ~ $ calendar -B 34 -t 20190109 solene@t480 ~ $
