For the second straight year, Cinco de Mayo falls on an awful day for celebrating (this year, it’s a Monday…).To save everyone’s party from having a “case of the Mondays,” Dos Equis and The Most Interesting Man have declared Friday, Dos de Mayo (May 2), the official kick off to a weekend full of celebrating Cinco properly.

The Most Interesting Man will be kicking off the news with a new national TV commercial airing Friday— but, of course, at HOMBRE you see it before everyone else! Check it out here: YOUTUBE: Most Interesting Man on Cinco de Mayo.

Just in time for the Cinco season, Dos Equis is launching Dos-A-Rita, a ready-to-serve lager margarita made with 100 percent real Agave nectar and lager beer. Inspired years ago by bars in San Antonio, the same recipe that created a local legend will now be available outside of Texas for the first time from Dos Equis. Fans can purchase Dos-A-Rita in select regions at retailers starting this month.

Throughout April, the Dos de Mayo campaign will feature new “Most Interesting Man in the World” television & radio spots created specifically for the holiday. The television spot airing nationally features the iconic character giving a nod to the Dos de Mayo season with the proclamation: “Don’t rush into Cinco. Start with Dos.”

Dos Equis is also giving its traditional Lager and Ambar bottles a makeover with limited-edition label designs inspired by its Mexican heritage. The new Cinco de Mayo designed labels will be available nationwide wherever Dos Equis is sold.

“Dos de Mayo is back, and with Cinco de Mayo falling on a Monday, we’re bringing the party to our fans all weekend long,” said Gwendolyn Boyce, Brand Director for Dos Equis. “Whether it’s with Dos-A-Rita, the new spot, or our contest with Rolling Stone, we’re putting our own twist on Cinco.”
