This unique ceremony is held to thank the Gods for the creation of arts and all forms of creative expressions related to the arts. On this day, offerings and prayers are presented to musical instruments, shadow puppets and the Barongs. Those who own shadow puppets will also perform a special ceremony accompanied by the shadow puppet theatre and musical instruments. Balinese who are born during the week of Wayang in the Balinese calendar will undergo a purification rite called Melukat or Ruwatan, as the Balinese believe that people born on this day would incur the wrath of Lord Kala unless ceremonies are conducted and Wayang Sapuh Leger performances are staged. This holiday is also known as Odalan Wayang or the birthday of Wayang and falls every 210 days.
