Date formula

jgneely72151 · 09/25/23

Hello!

I currently have 2 columns on my sheet, one where I enter date processed and date expired which has a formula to calculate 1 year expiration from date processed. I have been asked that no matter what date I process, it needs to expire the last date of that month. So for example,

date processed = 9/5/23
date expired should be 9/30/23

How would I write this formula AND how would this formula know the actual last day of the month, especially leap year?

Any assistance is appreciated as I do not want to enter this in manually each time.

Thanks!

@jgneely72151 I forgot to deal with December. The formula should be:

=IF(MONTH([Date Processed]@row) = 12, DATE(YEAR([Date Processed]@row) + 1, 12, 31), DATE(YEAR([Date Processed]@row) + 1, MONTH([Date Processed]@row) + 1, 1) - 1)

Will this work?

=DATE(YEAR([Date Processed]@row) + 1, MONTH([Date Processed]@row) + 1, 1) - 1
