Get week number starting on Monday where Week 1 is the first week with at least 4 days

[Ryan_Buckley]

Here’s the same thing that I’m looking to do with timeanddate.com

timeanddate.com

Year 2021 Calendar – Canada

I’ve tried a few workarounds but there doesn’t seem to be a lot of low-level date functions in Airtable that I can use to do this.

Any suggestions would be greatly appreciated. Thanks!
