National school holidays in the United States include all federal holidays, Thanksgiving, Christmas, spring break and summer break. Federal holidays include Martin Luther King, Jr. Day on the third Monday of January, Presidents' Day on the third Monday of February, Memorial Day on the last Monday of May, Independence Day on July 4, and Labor Day on the first Monday of September.
Columbus Day on the second Monday of October and Veterans Day on Nov. 11 are also federal public holidays. Depending on the state and demographics and whether the school is public or private, schools may also observe state holidays and religious holidays. School districts have the flexibility to set their vacation schedules.
Americans celebrate Thanksgiving Day on the fourth Thursday of November. With many schools declaring the day before, Wednesday, a half day or a holiday altogether, Thanksgiving turns into a five-day holiday weekend. Typically, Christmas break starts on Dec. 23 or earlier and ends on the first weekday after New Year's Day. Some schools start on the first Monday after New Year's Day.
Spring break is a one-week holiday around the Easter celebration in April, while the summer break is an 80- to 90-day holiday that starts anytime from end of May to late June and ends from mid-August to Labor Day, depending on the region or state.
