Filter by Date based on Current Date/time

Hey forum,

I have a table that I’m trying to add a filter to to search for expiration dates occurring within 3 time frames: less than 3 months, 3-6 months, and more than 6 months from the current date/time - these options are part of an option set. I’m having an issue trying to figure out how to setup the constraints to pull this off. Or should this be occurring as a conditional on the table? Any help is appreciated!!
