A civic holiday, civil holiday, public holiday, legal holiday, or work holiday is a day that is legally recognized and celebrated as a holiday in a particular sovereign state or jurisdictional subdivision of such, e.g., a state or a province. It is usually a day that the legislature, parliament, congress, or sovereign has declared by statute, edict, or decree as a non-working day when the official arms of government such as the court system are closed. In federal states there may also be different holidays for the constituent states or provinces, as in the United States where holidays that were established by the federal government are called federal holidays. Such days may or may not be counted in calculating the statute of limitations in legal actions and are usually days when non-custodial parents are given alternating visitation or access to their children from a prior marriage or relationship according to a parenting schedule.
