Formula to return the first day of the month for the prior 13 months?

chapmandb

I'm building a rolling 13 month graph and I need a formula that will take today's date and provide me with the first day of the prior month, first day of 2 months ago, first day of 3 months ago, etc. so that I can then do a lookup from my master sheet to pull the right data from those respective months. The formula would go in the MM-YY column. Thanks!

I figured it out. Posting here in case it might help someone else: =IFERROR(DATE(YEAR([MM-YY]45), MONTH([MM-YY]45) - 1, 1), DATE(YEAR([MM-YY]45) - 1, MONTH([MM-YY]45) - 1 + 12, 1))

[MM-YY]45 is the "Current" date field 06/09/23 in the image above.
