2024 Presidential Election Calendar

The Democratic National Convention is scheduled for late August.

The Republican Party held its national convention in July at which it formally nominated former President Donald J. Trump and Sen. JD Vance of Ohio as its presidential and vice presidential candidates.

Mr. Trump and Vice President Kamala Harris, the presumptive Democratic nominee, will face off in a prime-time matchup hosted by ABC News on Sept. 10. After President Biden’s exit from the race — spurred in part by his June 27 debate performance — Mr. Trump had initially canceled this date, but changed his mind.

Mr. Trump has proposed two other dates, to which Ms. Harris has not yet agreed.

A majority of voters live in states that allow voting by mail, though some states require an excuse — like travel, work or illness — to be eligible to receive a ballot. Many states have deadlines to request mail ballots that are less than two weeks before Election Day, but the Postal Service recommends that voters request them as early as possible and mail them at least one week before their state’s ballot return deadline.

To be counted, ballots in some states must be postmarked by a certain date, while some states require them to be received by a certain time (often by poll close time on Election Day). This deadline may be different for ballots returned in person, as opposed to through the mail. Check with your county officials for more details.

Starting in September, voters can visit a polling location or cast their absentee ballot in person in states that allow one or both methods. For many states, early voting rules vary by county, so check with local officials for details.
