亡灵节, or Día de los Muertos, is a traditional Mexican holiday celebrated on November 1st and 2nd. It honors deceased loved ones, blending indigenous customs with Catholic influences. Families create altars, or ofrendas, adorned with photographs, favorite foods, and marigolds to welcome the spirits back to the living world. During this time, people visit cemeteries to decorate graves and hold vigils. The holiday emphasizes remembrance and celebration rather than mourning, reflecting a belief that death is a part of life. Sugar skulls and colorful decorations are common symbols, representing the joy and continuity of life and death.
