US election result: What time will we know who the winner is?

It’s been well over a year since Donald Trump and Hillary Clinton each announced they were running for president. Now, we’re finally in the campaign’s final hours.

The US election is on November 8, American time, but in Australia we will be seeing most of the action on Wednesday, November 9.

Otherwise, here are the key times you need to know and the states you need to watch as we await a winner:

Tuesday, 4pm AEDT

The first voting will begin in the town of Dixville Notch, New Hampshire, which has a population of 12.

They have a pretty cool tradition of voting at midnight, which means its results are known before the rest of the country.

Tuesday, 10pm AEDT

Polls open in some states on the east coast.

Depending on the state, polling booths will open between 6am or 7am local time and close between 7pm or 8pm. (If you’re in line when polls close, you still get to vote.)

Fun fact: there are six different time zones across the United States, but just to make things nice and complex there are 13 states operating with split time zones.

The point is, most voting will take place overnight Tuesday, Australian time.

Wednesday, 11am AEDT

Polling stations will start to close in eastern states.

Once the polls have closed, there will be a projection for each state based on opinion polls taken throughout the day. They are a good indication of the results but not always correct.

The key results to watch out for at this time are from swing states FloridaNew HampshireVirginia

Wednesday, 11:30am AEDT

Polls close in two more battleground states — North CarolinaOhio

In other words, this is when we might get an indication of how well Mr Trump is faring.

Wednesday, 12:00pm AEDT

Polls close in 18 states, the most important being Pennsylvania

This is also when the final polls close in Florida

Wednesday, 1:00pm AEDT

Polls close in 10 states, including WisconsinColorado

While Mrs Clinton is considered the favourite to win Wisconsin, a Trump upset there would point to a tight race across the board.

The final polls close at this time in Texas

Wednesday, 2:00pm AEDT

Voting ends in swing states NevadaIowa

If Mr Trump doesn’t win Iowa, he’s seen as being pretty much done. Although by this time, we should have a decent idea of how the night has played out.

Wednesday, 3:00pm AEDT

Voting closes in states on the west coast, including California

Polls close in Alaska

When will the winner be named?

The close of the polls on the west coast (i.e. 3pm AEDT

The magic number is 270 — that’s the number needed for a majority in the electoral college, where each state (plus Washington DC) is awarded a certain number of electoral college votes based roughly on size and population

The first candidate to reach 270 wins, and swing states dictate the outcome.

Like in Australia, the losing candidate will usually call the winner to concede defeat once that number has been reached.

Where will Clinton and Trump be?

Mrs Clinton and Mr Trump haven’t confirmed when or where they will cast their ballot, but they are both expected to do so somewhere in New York.

Mrs Clinton’s ‘Hillary for America Election Night Event’ will start at 6pm at the Jacob K. Javits Convention Centre in New York.

The ‘Donald J. Trump Victory Party’ will start at 6.30pm at the New York Hilton Midtown.

So, what if we don’t get a result on the night?

This happened in 2000 in the election between president George W. Bush and former vice president Al Gore.

Mr Bush won the presidency after a recount in Florida, via a challenge in the US Supreme Court.

Barack Obama remains president until January 2017, so there’s plenty of time for recounts if need be.

What if they tie?

There is a possibility that two candidates will get 269 electoral college votes. It’s also possible no candidate will reach the 270 target.

But don’t worry, America’s constitution covers these scenarios.

If no single candidate receives an electoral college majority, the House of Representatives has to decide

Each state delegation has to make the decision, not each representative. Current numbers favour the Republicans, but the vote wouldn’t take place until January, when the next Congress is sworn in.

If there is still no winner, the job goes to the vice president-elect. However it will be up to the Senate to vote

If we still have no winner, the presidency goes to the Speaker of the House

When will the winner be given the keys to the White House?

Not for a while.

The new president and vice president will be sworn in at noon on January 20

That might seem like a long wait, but up until 1937 presidents weren’t usually sworn in until March because it took so long to count and report the results.

And if after all that, you fear US election withdrawal, don’t worry — after that it’ll be less than two years until the mid-terms!
