Election Day in the United States is the annual day for general elections of federal, state and local public officials. With respect to federal elections, it is statutorily set by the U.S. government as "the Tuesday next after the first Monday in November" of even-numbered years (i.e., the Tuesday that occurs within November 2 to November 8).
Federal offices (president, vice president, and United States Congress) and most governors (all except for Kentucky, Louisiana, Mississippi, New Jersey, and Virginia) and state legislatures are elected in even-numbered years. Presidential elections are held in years divisible by four, in which electors for president and vice president are chosen according to the method determined by each state. Elections to the U.S. House of Representatives and the U.S. Senate are held every two years. All representatives are elected to serve two-year terms. Senators serve six-year terms, staggered so that one third of senators are elected in any given general election. Elections held two years after presidential elections are referred to as midterm elections. Terms for those elected begin in January the following year. The president and vice president are inaugurated (sworn in) on Inauguration Day, which is usually January 20.
