Trying to backdate 6 months or 180 days from a specified date.
I'm able to go back 6 months without any issues, but I want to return that date for the 1st day of the month.
=DATE(YEAR([1st day]@row), MONTH([1st day]@row), 1) - 180
If it backdates into last year, it doesn't go to last year and instead changes it to the current year.
=DATE(YEAR([1st day]@row), MONTH([1st day]@row-180), 1)
I'm pretty sure I'm missing something simple, but can't figure it out. Please help. Thank You.
