Tuesday, Sept. 22 marks National Voter Registration Day, “a nonpartisan civic holiday” that urges Americans to register to vote.

First established in 2012, the fourth Tuesday of every September is dedicated to either registering voters or educating other Americans on the voting process, including mail-in ballots, early voting options, and important deadlines.

Each state has a deadline for registering to vote. Twenty-one states and Washington, D.C., have enacted same-day voter registration, which means a qualified resident can register to vote and cast a ballot on the same day.

With 42 days to go until the 2020 election, here is the voter registration deadline for each state:
