Early voting, also called advance polling or pre-poll voting, is a convenience voting process by which voters in a public election can vote before a scheduled election day. Early voting can take place remotely, such as via postal voting, or in person, usually in designated early voting polling stations. The availability and time periods for early voting vary among jurisdictions and types of election. The goals of early voting are usually to increase voter participation, relieve congestion at polling stations on election day, and avoid possible discrimination against people with work and travel schedules that may effectively prohibit them from getting to the polls during the hours provided in a single election day.
