Nyepi Day (Balinese New Year) is also determined using the Balinese calendar, the eve of Nyepi falling on the night of the new moon whenever it occurs around March/April each year. Therefore, the date for Nyepi changes every year, and there is not a constant number of days difference between each Nyepi as there is for such days as Galungan and Kuningan. To find out when Nyepi falls in a given year, you will need information on the cycles of the moon for that year. Whenever the new moon falls between mid-March and mid-April, that night will be the night of great activity and exorcism island-wide, while the next day will be the day of total peace and quiet, where everything stops for a day.
