Rules handling on holidays

Hi

any idea how to handle rules dependend on holidays?

My requirement: SUN-THU Internet access should be blocked for my kids at a given time - say 9 pm. FRI-SAT it is allowed until 11pm. Currently this works fine with two rules which are active on those week days and times.

But... on holidays i have to manually adjust those rules every time... is there any idea to include a calender having public holidays to dynamically handle the scheduling? For example tomorrows Monday us a public holiday and in this case internet access should be allowed until 11pm - in case of no public holiday until 9pm.

Any ideas/tips how to set this requirement up?

Thanks a lot

Mathias
