I've taken it upon myself to make a list of holidays for every day of the year. Then the younger Newgrounds users have an excuse to skip school. Yeah, don't do it, though. To keep it simple, I am doing 2014 only in this post. (Maybe I'll do 2015 next year.) This applies to all countries. Feel free to comment and tell me what else to add. Will update once a day (1 month per day) until I have all months. I won't add the country unless needed. I will add religious holidays, too. Now you can celebrate every day!

Yeah, I only put in holidays I know about. That's the Kagami Biraki, a celebration where people in Japan decorate mirrors. I don't understand it very well, but that's what they do. I learned about that one 20 years ago in kindergarten for a Japanese culture presentation.
