cinco-de-mayoCinco de Mayo is on Sunday, which means muchos Mexican-themed, cerveza-fueled fiestas are planned Saturday and Sunday across Long Island to celebrate the national holiday for America’s allies south of the border.

The events range from fundraisers for Superstorm Sandy survivors and family events for the kids to local bars and restaurants offering specials on burritos, margaritas and Coronas—so break out that souvenir sombrero from Cancun.

But, before leaving the house in a poncho, here’s a quick North American history refresher lesson:  Cinco de Mayo is not—like some people mistakenly believe—Mexican Independence Day, which is Sept.16.

The holiday commemorates the Battle of Puebla, when Mexican forces turned back invading French troops in 1862—a symbol of resiliency for the world’s most populous Spanish-speaking nation.

And for those who still remember their high school Spanish 101, here’s a potentially useful bonus factoid—a Mexican saying that may come in handy on the Long Island Rail Road this weekend: “A boca de borracho, oídos de cantinero.”

It translates to “the mouth of drunk, ears of barman.” It basically means ignore the loud drunks.
