The Cinco de Mayo holiday is right around the corner, so now is a good time to read up about the origins of the holiday. Many people incorrectly assume that Cinco de Mayo is a celebration of Mexico’s independence, among other incorrect notions. (Mexico’s indpendence day is September 15th)
Here is a website that has a great overview of Cinco de Mayo: http://www.vivacincodemayo.org/history.htm
Be sure to check and see if there is a local celebration or parade for Cinco de Mayo in your local city. Many have long traditions of yearly celebrations held on this day, or on a day close to May 5th.
