**Your software** My Mautic version is: 5.03 My PHP version is: 8.1 My Database type and version is: mysql 8 **Your problem** My problem is: I am trying to create a segment filter that is based upon a rolling date. In other words, when a contacts last\_date (custom field) is 30 days or less from “todays” date, add them to the segment. Kind of like a date difference function that returns number of days? ---

Hi, that would be 30 days or less then now: last\_date ‘less or equal then’ -30 days Why? A date 30 days ago is -30 days Anything older then that is -31, -32, -100 etc. Which means “-30 days or less”
