Counting Months Formula


Hello! I have a counting question I need some assistance with.

I'm trying to count the number of months between two dates (Date Opened and Date Closed). I currently have this formula:

=ROUND(((NETDAYS([Date Opened]@row, [Date Closed]@row) / 365) * 12), 0)

It works beautifully, but we've updated our process from counting in 30 day increments, to counting the number of months involved in the process (e.g. if Date Opened is 12/31/21 and Date Closed is 01/01/2022, it's technically two months).

Is there a formula that can calculate this? I can't find anything online.

Thank you!!
