Criteria to Delete or Move Files After Certain Date

I would like to create one or more rules to automate deleting or moving files after a certain date.
For example, I would like to automatically delete copies of Insurance Policies after the expiration date. Likewise, I keep confirmation that I've returned something until I receive a refund.
I'm sure there's a way to do this with Hazel but I'm not sure where to add the criteria for Hazel to match.
For pdf files, I could add a text string such as "Move after: [date]" or "Delete after: [date]"
For all files including pdf's, I could add either of these to the Comments area from the Get Info window in Mac OS Finder.
Will either method work? is one method better than another?
Thank you for any advice or suggestions.
