Election Day in the United States is the day set by law for the general elections of public officials. It occurs on the Tuesday after the first Monday in November. The earliest possible date is November 2 and the latest possible date is November 8. The 2012 election was held on November 6, 2012. For federal offices, Election Day occurs only in even-numbered years. Presidential elections are held every four years, 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 United States House of Representatives and the United States Senate are held every two years; all Representatives serve two-year terms and are up for election every two years, while Senators serve six-year terms, staggered so that one-third of Senators are elected in any given general election. General elections in which presidential candidates are not on the ballot are referred to as midterm elections. Terms for those elected begin in January the following year; the President and Vice President are inaugurated on Inauguration Day, usually January 20.
