A guide to all the important dates for the 2020 US presidential election.

The United States is less than three months out from the Iowa caucus, the kick-off event for the 2020 presidential primary and caucus voting season.

After Iowa, a series of primaries and caucuses will be held, leading up to the Democratic and Republican conventions in which the parties will formally choose their candidates.

Until the conventions, at least eight more Democratic debates will be held. After the conventions, at least three presidential debates and one vice presidential debate will take place.
