Nyepi, also known as Day of Silence, is a Balinese holiday held every Isakawarsa ("new year") according to the Balinese calendar, and it can be traced as far back as 78 A.D. The observance includes maintaining silence, fasting, and meditation for Balinese Hindus. The following day is celebrated as New Year's Day. After Nyepi, youths in the village of Sesetan in southern Bali practice the ceremony of omed-omedan, or "kissing ritual".
