The federal holidays listed above are designated by the United States Congress in Title V of the United States Code (5 U.S.C. 6103). Congress has the authority to designate holidays for government (federal) institutions so many other state and private institutions like businesses, banks, schools, and post offices have followed along and have included federal holidays as paid days off for their workers. Many state and local governments will have additional holidays off for their workers depending on their own local culture and history. The first official federal holidays began back on June 28th 1870 when congress wanted to correspond to state holidays that were in place and made federal holidays for federal employees located in the District of Columbia law. Later in 1885 the first four Federal Holidays (New Year's Day, Independence Day, Thanksgiving Day, Christmas Day) where extended to all federal employees in the country.
