Día de los Muertos, or Day of the Dead, is a traditional Mexican holiday that celebrates life and death and honors deceased loved ones. It’s traditionally celebrated on November 1 and 2, and sometimes over a three-day period from October 31 to November 2; however, celebrations can take place anytime in the Fall. The holiday combines the ancient Aztec tradition of honoring ancestors with All Souls’ Day, a holiday brought to Mexico by Spanish invaders in the 1500s. It’s a blend of Catholic tradition and Mexican mysticism that commemorates death as another part of life.
