Phi Ta Khon (ผีตาโขน) is the most popular festival in Loei province in the Northeast of Thailand (Issan). It is held in Dan Sai district and lasts for three days. The date for this event changes each year, but it is always sometime between March and July. The exact date is determined by two mediums (mor pii/หมอผี ) – Jao Por Guan and Jao Mae Nang Tiam. This event is part of a larger celebration known as Bun Luang which also includes Bun Bang Fai (the rocket festival).
