There is a lot of confusion about Cinco de Mayo, which has pretty much become more of a frat house-styled holiday of downing tequila shots rather than any kind observant day concerned with Latino pride.

The holiday is not, as some people think, Mexican Independence Day. That actually takes place on Sept. 16.

Back in 2005, in an effort to celebrate Mexican-American heritage, Congress passed a resolution that declared Cinco de Mayo to be an official national holiday.

And before that, in 1998, the United States Post Office had already issued a Cinco de Mayo stamp featuring two colorful folklórico dancers.

May 5 is actually the anniversary of the Battle of Puebla, which took place is 1861. In the course of that battle, Mexican liberal forces defeated an occupying French army along with its Mexican conservative allies.

According to Time, one of the earliest areas in the U.S. that celebrated Cinco de Mayo was a Southern California town called Corona in 1923.

Corona was once known as the “Lemon Capital of the World,” and the holiday just so happened to occur at the time of year when the harvesting was over and the Mexican laborers, who needed a break, just got paid for their work so they had a little extra spending cash on hand.

Although Cinco de Mayo has a bit of a reputation of being a day that is all about booze, it does not have to be so.

In Chandler, Arizona, as reported by AskMen, some people celebrate May 5 by racing chihuahuas.
