2009 2008 Holiday Calendar 2008 2009

The tables below list the calendar days and dates of various calendar holidays and observances. The legal status of holidays varies from state to state and the U.S. national Federal government. Some holidays are "fixed" - for example, Christmas is always December 25. Other holidays are fixed only to a particular day of the week in relation to a particular week of a fixed month - for example, Mothers Day is always the second Sunday in May. The most complicated of calendar holidays is Easter Sunday - a "movable feast" that can occur in March or April and is determined by a complex mathematical procedure. The calendars below have a total of 13 fixed calendar date holidays + 8 holidays that are fixed to a certain day of the week - Sunday (2), Monday (5), and Thursday (1) - and the complex Easter Sunday holiday along with Good Friday. Holiday data is presented for calendar years 2006, 2007, 2008, 2009, and 2010. Also, a Holiday Calendar near the bottom of the page can be used to find the dates of these holiday observances for any year. A US holiday list calendar follows.
