I hope your sample data isn't containing a bunch of legitmate license plates. not the most compromising data but I would recommend blacking out or replacing them with test data if it isn't already.

anyway. you're looking for the DateDiff() function. for example:

If(DateDiff('day', Date(DateTimeNow()), [Date]) >= 21, "21 days or more", "less than 21 days")
