All of these are handled by offloading the problem to a good library. It would be dumb to handle the 30/31 months oneself, failing to take everything else into

  Do you know any good library? Besides, my point was that I think time is such an essential data point, it should be handled directly by the language without the need to look for a library. Like sin() is directly accessible in every non-toy language.

    My current project has modest needs; there are some times in a database but I just make sure everything is handled as UTC internally, and converted on rendering (showing the timezone explicitly). There are some timedeltas (Python stdlib) involved, but they are expressed in days. As you notice, “one month from now” is ambiguous, and I think it is good that timedelta does not use that unit. So I haven't needed to go outside Python's stdlib (which mirrors a POSIX libc), even though I don't hesitate to do so. In other projects I've used clock_monotonic (POSIX, but needs a Python module or ctypes until the next Python 3 release), and either dateutil (if I need to do more advanced calendar math) or pytz (if I just need a timezone database).
