Day of the Dead, or Dia de los Muertos, is a vibrant and colorful celebration in Mexico honoring deceased loved ones. It takes place on November 1st and 2nd, coinciding with the Catholic holidays of All Saints' Day and All Souls' Day. Families build altars, or ofrendas, decorated with marigolds, candles, and photos of the deceased, and leave offerings of food and drink. The festivities also include parades, music, and dancing, creating a joyful and lively atmosphere to commemorate those who have passed away.
