"Holiday Conditions"

How difficult would it be to create a new module for "holiday conditions" where one could create a time condition that uses criteria like "the 4th Thursday of November" or be able to auto-calculate Labor Day, etc.?
I'm sure I'm not the only one who finds annual reprogramming of holiday closings into time conditions to be tedious.
Thoughts?

I have my system setup for
I have my system setup for all inbound routes going to a time condition called holiday then from that going into my normal working hours
then i just program the holiday condition that way it doesnt effect my normal working hours
Holidays
Well, of course... I'm sure we've all had to do that for our programming.
My point is that the time groups can't be programmed like "4th Thursday of the month" or other non-static-dates like President's Day, Lee-Jackson Day, Memorial Day, Labor Day, Independence Day (observed), Election Day, etc.
Under the current method, all dates for time conditions must be (re)programmed every year for the coming year--something that seems silly when most other computer-based timing systems can handle at least things like "2nd Tuesday" or "Friday of the 3rd full week of the month" or "the business day following the 20th of the month"
