Tournament time in college basketball is one of those special times during the year when excitement and suspense are at their peak. From the opening-round upsets all the way to the national championship game, March Madness takes hold of an entire country and doesn't let go.

The first stop on the road to this year's Final Four – for the men, it's in Phoenix; for the women, it's in Cleveland – begins with Selection Sunday, when the field of 68 teams is announced.

The NCAA Selection Committees will take all the conference champions who qualify automatically and then extend the necessary number of at-large bids to the remaining schools to fill out the full field. The teams will then be divided into four regions and seeded from 1 to 16, with eight teams competing in play-in games for the last four spots.

Is Selection Sunday a week later than usual?

It does feel that way. But the NCAA Final Four is always held during the first weekend in April, and this year that pushes things to their latest possible dates on the calendar.

Working backwards, with the tournament running over the course of three weekends, Selection Sunday falls on St. Patrick's Day, March 17 – which many basketball fans associate with the tourney's first weekend.

Who won March Madness tournaments last year?

Men: The Connecticut Huskies defeated the San Diego State Aztecs 76-59 at NRG Stadium in Houston.

Women: The LSU Tigers defeated the Iowa Hawkeyes 102-85 at the American Airlines Center in Dallas.
