This is indeed a bug (specifically in gnulib's date parsing module, but easier to track here). It seems the existence of the "am/pm" string causes the parser to take a slightly different rule, then reject additional relative values, unless they have a unit, e.g.: $ date --debug -d '8pm +5 days' date: parsed time part: 08:00:00pm date: parsed relative part: +5 day(s) [...] Contrast it with a different (and confusing) rules when there is no "am/pm", the relative number is always taken as the time zone, e.g.: $ date --debug -d '8:00 +5 days' date: parsed time part: 08:00:00 UTC+05 date: parsed relative part: +1 day(s) date: input timezone: parsed date/time string (+05) [...] (from https://bugs.gnu.org/17161#31 ) I hope to get to this bug soon. -assaf
