Mid-june till september off for schools. July and august off for college students. One week prior to christmas and one week some time around easter off for both. Four weeks paid yearly vacation for the 9-to-5ers. Two weeks additional paid vacation for working students finishing their graduation works. National holidays and sickness don't count towards your vacation time. If a national holiday happens to be in weekend, friday or monday is usually free.

Honestly, the more I read about US working conditions, the more I feel like people there are deliberately misinforming everyone else in attempt to reduce immigration and competition on job market.
