The United States does not have national holidays (i.e., days where all employees in the U.S. receive a day free from work and all business is halted). The U.S. Federal government can only recognize national holidays that pertain to its own employees; it is at the discretion of each state or local jurisdiction to determine official holiday schedules. There are eleven such "Federal holidays", ten annual and one quadrennial holiday. The annual Federal holidays are widely observed by state and local governments; however, they may alter the dates of observance or add or subtract holidays according to local custom. Pursuant to the Uniform Holidays Bill of 1968 (taking effect in 1971), official holidays are observed on a Monday, except for New Year's Day, Independence Day, Veterans Day, Thanksgiving, and Christmas. There are also U.S. state holidays particular to individual U.S. states.
Most retail businesses close on Thanksgiving and Christmas, but remain open on all other holidays. Private businesses often observe only the "big six" holidays (New Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving, and Christmas). Some also add the Friday after Thanksgiving, or one or more of the other federal holidays.
