One way to tackle this, maybe, is to start with the end year, multiply by 12, then add the end month number.
From that, subtract the start year multiplied by 12, then add the start month.
Then, add 1 to that result.

From your example thatâ€™d be (202312+10) - (202312+8) + 1 = 24,286 - 24,284 + 1 = 3

Then use a repeater, starting at 0 and repeat the number of times from the previous answer, 3.
From each bundle of the repeater, which in this case is going to be 0, 1, 2, start with your start date and add i months.
August 2023 + 0 Months = August 2023
August 2023 + 1 Month = September 2023
August 2023 + 2 Months = October 2023

Thanks Donald, that will work. It is strange that there isnâ€™t an easier way to do it. Curious too to see other ways to tackle it but much appreciated and thanks for going the extra mile with the blueprint.

The problem, I think, is if the end date is something like Jan 2025 and the start date is Aug 2023 then itâ€™d be 1 - 8 = -7.
-7 doesnâ€™t correctly represent a 17-month span.
