Early voting
Early voting is similar to "no-excuse" absentee voting. In many U.S. states, the period can vary between four and fifty days prior to Election Day. Early voting in person is allowed without excuse required in 39 U.S. states and in the District of Columbia (DC). Absentee voting by mail without excuse is allowed in 27 states and DC. In 16 states, an excuse is required. Vote-by-mail is the default form of voting in 7 states and one of those states (Oregon) conducts all voting by mail.
