Death customs refer to the rituals and practices that societies observe when a person dies. These customs can vary widely across cultures and may include specific mourning periods, burial practices, and memorial services. For example, in some cultures, the body is buried within a few days, while others may hold a wake or vigil to honor the deceased. Many death customs also involve symbolic gestures, such as lighting candles or offering food to the spirits of the dead. In Mexico, the celebration of Día de los Muertos honors deceased loved ones with altars, while in Japan, families may conduct a Buddhist ceremony to guide the spirit.
