431 | ``date2 = date1 - timedelta`` | Computes *date2* such that ``date2 +         |

444    ``timedelta.days < 0``.  Afterward ``date2 - date1 == timedelta.days``.
450    This isn't quite equivalent to date1 + (-timedelta), because -timedelta in
451    isolation can overflow in cases where date1 - timedelta does not.
456    timedelta.microseconds are 0, and date2 + timedelta == date1 after.
459    In other words, ``date1 < date2`` if and only if ``date1.toordinal() <
