There are, and way too many in my opinion.

I just don't pay attention and ignore them.
There were over 30 holidays, but they got reduced because there were too many days free for people and it was a hindrance. Nothing could get done properly since when you thought there would be 5 business days it was actually only 4 or 3 business days followed by another week with 4 or 3 business days. Things that would usually get done in 5-7 business days took 2 or more weeks to get done because of the holidays. It was a real hindrance and I still think that even when they have been reduced it is a hindrance.
You realize they are a hindrance when you need something from the government ASAP and they take an eternity to serve you simply because they are off in holidays.
