Cesar Chavez Day is observed every March 31 in the United States to celebrate the birth and legacy of Cesar Chavez, a prominent labor movement leader and civil rights activist born on March 31, 1927, in Arizona. Chavez began his activism in 1952 with the Community Service Organization and later founded the National Farm Workers Association in 1962, which became the United Farm Workers. His efforts included organizing significant strikes for better wages and working conditions, notably achieving higher pay for farm workers in the grape and lettuce industries. Although not recognized as a national holiday, many schools, community colleges, libraries, and state government offices close in his honor. Celebrations take place in various states, including Michigan, Arizona, Nebraska, and New Mexico, highlighting Chavez's role as a national hero and symbol of the fight for Mexican migrants' civil rights.
