It sounds like you might be able to calculate the date based on the
current date. You would need to formula a precise rule for calculating
the two dates based on the date the script is being run. (And you may
still need another script if you need to be able to handle exceptions.)
If the script updates stuff than you may need to put in some extra care
in making sure that it can't be run twice or after skipping a time period
without some sort of override.
