Have you ever wondered about the weird little holidays each month? Or about which month observes which thing? I know I love having this info for our HS as it's FUN! (It was national doughnut day the other day!!). Here are some lists that might be of help:
National Awareness Months
Monthly Holidays (with great educational links)
Crazy Complete list of US Holidays, Observances and Celebrations
Furthermore, I like comparing the holidays in our country/religion to those around the world.
