Everyone ready for
Pchum Ben (បុណ្យភ្ជុំបិណ្ឌ)?
In Cambodia, the 15 days prior to the 15th day of the tenth month in the Khmer calendar, at the end of the Buddhist lent, or Vassa, lead up to Ancestor's Day or the Hungry Ghost Festival. The last day of the 15 is Pchum Ben and starts a two-day public holiday.
On the first day of Pchum Ben, the gates of hell are opened and the devil releases all the ghosts, some of who are ancestors of the people. Monks chant the sutras in Pali (not Khmer) before the gates of hell open releasing the hungry ghosts.
