Where 2,629,746 fits
Why 2,629,746 is special
A twelfth of the mean Gregorian year — about 30.44 days, a length no actual month has. It exists because software has to convert 'a month' into a duration and the calendar refuses to supply one, which is the same reason adding a month to 31 January has no agreed answer.
