This app contains a national calendar of all 2023 federal and state holidays for the United States. These dates may be modified as official changes are announced, so please check back regularly for updates.

Federal holidays in the United States are public holidays that have been recognized by the federal government, and are applicable to federal employees. State holidays are public holidays recognized by states – and often (though not always) include the same holidays recognized at the federal level.

With the exception of Independence Day, Thanksgiving Day and Christmas Day, all federal holidays are observed on a Monday. This is in accordance with the Uniform Monday Holiday Act which is intended to move holidays to a Monday whenever possible in order to allow federal employees to have a three-day weekend.

States are not required to observe federal holidays. Not only are states allowed to opt out of observation of these holidays, but states are also given the opportunity to declare state holidays if they so choose.

Although there are no federally-mandated holidays currently observed in the United States, most states choose to observe federal holidays. Some states observe versions of holidays that are related to the federally recognized holidays without being identical.
