WEEKNUM() day

For WEEKNUM(), does a week begin on Sunday or Monday? The help page doesn’t specify and I’ve got a Report running on Sunday at 1200 that checks if a record has already been created manually.

WEEKNUM() shows the week number not the number for a specific day

Let me put it another way

Is Sunday 25th Oct 2020 in week 43 or week 44?

As WEEKDAY() has Sunday as day 1

Week 44

So WEEKDAY() starts on a Sunday and WEEKNUM() Starts on a Monday

WEEKNUM() starts on a sunday. See screenshot below
