Cinco de Mayo (Fifth of May) is a popular event in the U.S. commemorating the Battle of Puebla in 1862 when Mexico defeated the French. The first Cinco de Mayo celebrations were held a year later in southern border states like California, and continue today celebrating Mexican-American culture. This year, locals can experience the richness of Spanish traditions at the Windsor Cinco de Mayo Fest. This is a free, family-friendly event where visitors can immerse themselves in the vibrant spirit of cuisine, drinks, and live music. The event features traditional performances of dance and mariachi music brought to you by local artists. Viva la fiesta con comida, cultura, and musica! Saturday, May 4. 2–8 p.m. Windsor Palms Plaza, 8465 Old Redwood Hwy., Windsor. windsorchamber.com.
