calendar.IllegalMonthError docs omit IndexError base class #148663
Description
The documentation for calendar.IllegalMonthError describes it only as "a subclass of ValueError", but the source code defines it as class IllegalMonthError(ValueError, IndexError):.
The IndexError base class is intentional for backwards compatibility (see the source comment in Lib/calendar.py), but this is not mentioned in the docs. Users catching IndexError for bad month numbers won't know their code still works after 3.13.
