Otonan is a Balinese Hindu birth ceremony (ceremonial birthday) carried out in Bali, Indonesia.
Six months, or 210 days, after a child is born, the ceremony is carried out according to the Balinese Pawukon calendar, either during Sapta Wara, or Panca Wara.[1] The purpose of this ceremony is to make up for the errors and evils of prior life to achieve a more perfect life by expressing gratitude to ancestors and the deity Achintya.[2] It is led by a Hindu priest or family elder.[3]
During the first Otonan ceremony, a haircut ritual is typically involved and the ceremony is very festive.[4] The ceremony will continue to be celebrated throughout a person's life in conjunction with their birthday.[5]
A white thread bracelet called "beneng" is given after the Otonan ceremony is complete.
