From now until to June, 18 nights will confirm who the 2020 presidential candidates are.

It’s likely that President Donald Trump will be the Republican’s candidate, but the race for the Democrat’s nominee is still wide open.

The Iowa caucus on February 3 was the first election night of the year, followed by New Hampshire, Nevada, and South Carolina. Super Tuesday on March 3 is the biggest night, with 15 states and territories reporting results.

Business Insider previously broke down the differences between primaries and caucuses. In a primary election, voters can turn up to vote for whichever candidate they prefer. There are two types: open and closed. Open primaries mean anyone can vote, even if the person is planning to vote for Republicans later. Closed primaries only allow those who are registered in the party to vote.

Caucuses are when voters head to venues and listen to debates and candidates’ supporters, and then decide who to vote for. Candidates often need to meet certain thresholds in order to get delegates.

Here are all the important nights you need to know in the lead up to Election Day on Tuesday, November 3, 2020.
