The Day of the Dead is a holiday traditionally celebrated on November 1 and 2, though other days, such as October 31 or November 6, may be included depending on the locality. It is widely observed in Mexico, where it largely developed, and is also observed in other places, especially by people of Mexican heritage. Although related to the simultaneous Christian remembrances for Hallowtide, it has a much less solemn tone and is portrayed as a holiday of joyful celebration rather than mourning. Some argue that there are Indigenous Mexican or ancient Aztec influences that account for the custom, and it has become a way to remember those forebears of Mexican culture. The multi-day holiday involves family and friends gathering to pay respects and to remember friends and family members who have died. These celebrations can take a humorous tone, as celebrants remember funny events and anecdotes about the departed.
