Subject: [PATCH] Coding Standards: Cast `gmdate( 'w' )` to `int` before using
 as integer.

This addresses several instances of `gmdate( 'w' )` being used directly as an integer, when it's actually a numeric string. The issue is remediated by casting the value to `int` before use.

Affected functions:
* `get_calendar()`
* `get_weekstartend()`

Follow-up to [508], [1632].

Props justlevine.
See #52217.
