Cinco de Mayo is Sunday. And as you're drinking a blended margarita or eating authentic Mexican food like "Nachos Supreme" to celebrate it...it's probably good to know WHY.

Most people use celebrating Cinco de Mayo as a reason to drink giant margaritas. About three out of four people say they'll celebrate the holiday in one way or another...but only 10% of people know WHY.

A survey gave people five choices for what Cinco de Mayo is about, and the correct answer came in LAST.

39% said it's Mexican Independence Day, but it's not...that's September 16th...
26% said it's a general celebration of Mexican-American culture...
13% said it's a day for DRINKING...and 13% admitted they just had no idea...

The correct answer, which got 10% of the vote, is it's the anniversary of Mexico's victory over France in the Battle of Puebla on May 5th, 1862.

On Sunday, head out to your favorite Mexican restaurant...and amaze your friends and family that YOU know the real reason why Cinco de Mayo is celebrated.
