National Margarita Day focuses on appreciating the margarita, a tequila-based alcoholic cocktail. The origins of National Margarita Day are not well documented, although accounts of the day begin to emerge in the 1990s. A margarita is cocktail made of tequila, triple sec and either lime or lemon juice served in a cocktail glass with salt on the rim. Like the origin of the holiday, the origin of margarita is unclear as numerous bar tenders worldwide have laid claim on the drink's creation. Several bartenders and restaurant owners in Mexico allege to have created the drink for a female friend with a name similar to Margarita. Given that the cocktail contains tequila, the drink may have originated somewhere in Mexico. In fact, the tequila used in margaritas is made from blue agave plants that grow in Los Altos, Mexico. This holiday is observed every year on February 22nd. Source: https://www.wincalendar.com/National-Margarita-Day
