Presidents day is not a recognize paid holiday:
I don't think presidents day is a holiday that usually gets time and a half. When I was working, for a major corporation, we didn't get time and a half for any holiday and my husband only gets it on Easter, Thanksgiving, Xmas and new years.
But if you're on good terms with your boss, you can ask about it. You never know what will happen. I just wouldn't get my hopes up if I were you.
