 ::::It's saying that "months have either 28, 29, 30, or 31 days" is a falsehood.

But how many days had <insert your choice of month(s) during which a given system changed from Julian to Gregorian>? I think possibly, without looking up when each and every transition occured, below 20 days is possible. (As in the ''n''<sup>th</sup> of one month to the ''n''<sup>th</sup> of the next is less than 20 days, for the right month and a number of ''n''s.

 :Ideally, the standard library functions for a language would cover many of the "quirks" without the programmer having to worry about remembering the details. The required inputs for the functions would be sufficient to determine the necessary offsets. But programmers still have to be careful about some of the issues, and not all languages (and their libraries) are sufficient for all situations. When things like relativistic effects have to be taken into account, the usual languages (and their libraries) don't have the needed flexibility/complexity and precision.
