36145	FIRST_DAY_OF_WEEK setting not changing the Admin calendar widget	Phil Gyford	Sachi Jain	"The docs for the `FIRST_DAY_OF_WEEK` setting (https://docs.djangoproject.com/en/5.1/ref/settings/#first-day-of-week ) say:

  A number representing the first day of the week. This is especially useful when displaying a calendar. This value is only used when not using format internationalization, or when a format cannot be found for the current locale.

But if I set mine to `FIRST_DAY_OF_WEEK = 1` (Monday) then the calendar widgets in Admin still start on the default, Sunday.

I've tried with `USE_I18N` set to both `True` and `False`, with no change.

I posted this query in the Django Forum but we were stumped as to whether the documentation or the code was wrong in some way https://forum.djangoproject.com/t/django-admin-date-pickers-ignoring-first-day-of-week/38170/2"	Bug	assigned	contrib.admin	5.1	Normal			Claude Paroz Carlton Gibson Ryan Heo	Accepted	1	0	0	0	0	0
