Allow for relative season dates

We have rates for periods of time like "spring break" or "fall break" that occur every year but don't necessarily start on the same date.  We currently use spot rates for those but I'd rather be able to use recurring seasons and set the start and end time to relative dates like "second Saturday of the March"

YES! Date-specific seasons really don't make much sense in this industry!

Just in case someone's searching for this with different text, some less-common names for it would be: rule-based; recurrence; weekday-defined; floating date range.
