Pchum Ben, also known as Ancestor's Day, is a half-month period (fifteen days: from one Roach to fifteen Roach) of remembrance for dead family members, which traditionally begins between September and October (the tenth month of the Khmer Calendar). Pchum Ben is believed to be a time when the souls of our ancestors that passed away may come back to us. The course of their journey will be decided by their karma and by the offerings made by their living relatives during Pchum Ben.
