The Hungry Ghost Festival is celebrated on the 15th day of the seventh month of the lunar calendar. The seventh month is generally believed to be the month that restless spirits roam the earth and is sometimes referred to as Ghost Month.
However, it’s the 15th day that is officially Ghost Day and the day of the main festivities. On this day, the dead are believed to visit the living, while the living do their best to ease any suffering of past ancestors. This practice, known as ancestor reverence, is based on the belief that the dead possess a form of existence that may influence the living.
