Día de los Muertos is a traditional Mexican holiday celebrated every year from November 1st to 2nd to honor and remember loved ones who have died. It involves building altars with photos and offerings for deceased family members and lighting candles to guide their spirits back. Traditions include making pan de muertos bread, decorating with marigold flowers and papel picado artwork, and creating calaca skeleton figurines to symbolize life and death. The holiday is meant as a joyous time, not a sad one, and is celebrated in areas with Mexican heritage in the United States as well as other Latin American countries.
