According to the Vote Early Day 2022 official page:
Vote Early Day is a movement of nonprofits, businesses, election administrators, and creatives working to ensure all Americans know their options to vote early.
Vote Early Day was founded by MTV as a new civic holiday focused on helping every voter know how, where, and when they can vote early. Launched in the midst of a global pandemic, Vote Early Day became a critical resource to ensure no voter had to choose between their health and casting their ballot. In its first celebration, Vote Early Day attracted 134 premier partners and 2,700 general partners from every state in the nation. Over 3,000,000 voters cast their ballots on Vote Early Day alone.
