Google calendar question

[ratcreature]

Is there a way to tell the Google calendar it should repeat something weekly, except if it coincides with a local public holiday? Surely that is a common use case?

I once again ended up adding a repeated event, and then had to manually delete a bunch, that I ought to be able to exclude automatically, because Google already knows the dates of Christmas etc. It is really aggravating. (As you can probably tell I don't use Google calendar a lot, but I do like it for getting alarm reminders for appointments and such.)
