Which holidays are typical for your country of region? Everyday life and customs

With Christmas and New Year's Eve just around the corner, and Thanksgiving already done, I was wondering if there are some holiday(event)s which are typical for other cultures that I don't know of. So feel free to explain certain events throughout the year!

Well you probably know about Sinterklaas if you live in Belgium but Sinterklaas is a typical Dutch holiday celebrated mostly on december 5th but also in the weeks before. This tradition has been all over the news because there are 'zwarte pieten', black faces and there is a debate about if 'zwarte pieten' are racist.
