Counting weeks in a cycle


I need help with a formula to count weeks in a cycle.

The cycle start date was 5/1/23. End cycle will be 4/30/24 for example.

So I need to display the current week in the cycle as of today. I don't use the today function because it does not update unless the sheet is opened.

So instead of the today function I have a helper column called today date and have an automation put a date (which would be today's date in the "today date" column every day at 1am)

So how do I set up a formula to do that? So this week would be week 36.

    Hi @Jon Barto,

    If you have a cycle start and current date, would something like this work:

    =ROUNDUP(([Current Date]@row + 1 - [Cycle Start Date]@row) / 7)

    This will calculate the difference between the 2 dates and divide by 7 to give the week number. The +1 is so the start date is counted as week 1, rather than 0.

    Hope this helps, but if there are any problems or you've any queries, let us know.
