When Are March Madness Brackets Due?

Around 60 million to 100 million brackets are filled out each year.

March Madness brackets for the 2023 men’s and women’s NCAA tournaments came out on Sunday evening shortly after the Selection Sunday show.

Now it’s time for fans to begin filling out as many brackets as they want. Around 60 million to 100 million brackets are filled out by fans every year.

But, when are March Madness brackets even due?

That depends on each bracket challenge and the pool manager. Most brackets, though, must be complete before the first Round of 64 game, which begins at 12:15 p.m. ET on Thursday, March 16, for the men’s tournament or Friday, March 17, for the women’s tournament.

Most pools or groups don’t require the player to pick a winner for the First Four games, which take place at 6:30 and 9 p.m. ET on Tuesday, March 14, and Wednesday, March 15, for the men’s tournament, and Wednesday and Thursday, March 16, for the women’s tournament.

In order to make sure you don’t miss the deadline to turn your bracket in, make sure to check the challenge rules ahead of Thursday.

Here’s the full schedule for the men’s tournament.
