Date Calculation from Text String

jay_hl

I have the following date format in a field which is formatted as "27 year(s), 0 month(s), 19 day(s)", and a second field called Dataset Date which shows "2025-09-16".

Can someone help me with a Formula that calculates the date (in yyyy-mm-dd date format) that was "27 year(s), 0 month(s), 19 day(s)" ago?

Regards

Jay

Hi @jay_hl 

Here is one way of doing it. First you need to parse out the numbers for year, month, and day using Regex and Tokenize, then in one large formula subtract each section from your date - years first, then months, then finally days:
