It is always so hard to get a group photo at the holiday parties. Either someone is totally unruly, someone isn't there yet or people start leaving so when is the best time to take a picture to get everyone in it?

A new study has figured out the exact best moment to take a photo at a party, before they're all drunk and sloppy.

The best time is two hours and 36 minutes after the party officially starts.

So let's say you want to get a great photo with everyone at your Christmas party this year, and it starts at 7:00 P.M.

You need to give everyone some time to roll in, meet people they don't know, get into some conversations, and have a few drinks . . . but not TOO many.

And you'll want to take the photo at 9:36 P.M.

The study found that after three hours, people start to leave the party, or start to look more disheveled than when they showed up.
