The Eurovision Song Contest 2015 has finally arrived. Do you know where you're watching it?

Thursday marks the second round of semifinals in Vienna, with 17 teams from European countries vying for 10 spots in Saturday's final competition. Eurovision, an annual international contest in its 60th year, is expected to draw more than 180 million viewers worldwide -- many of whom tune in to see performers' crazy costumes and close competition. Thursday's semifinals were scheduled to start at 21:00 CEST, which is 3 p.m. EDT.

Much of the action takes place once the show concludes, when Eurovision viewers and a panel of judges each select half of the winners in each semifinal round, according to the rules page. Voting opens for 15 minutes after the end of the broadcast. Residents of the countries that perform Thursday -- as well as Germany, France and Spain -- can vote for their favorites in the Eurovision app, on the phone or via text message. You can vote up to 20 times, but you can't support your own country's artist.
