The island that celebrates Nyepi is Bali. Nyepi is a sacred Hindu holiday known as the "Day of Silence," celebrated as the Balinese New Year according to the Saka calendar. On this day, the whole island of Bali observes silence, fasting, and meditation for spiritual reflection and renewal. The celebration involves shutting down all activities, including turning off lights, stopping traffic, and refraining from noise to allow the island to rest and purify itself. Nyepi is a unique cultural and religious event deeply rooted in Balinese Hindu traditions and is only widely celebrated on the island of Bali in Indonesia. Nearby islands such as Lombok and the small Gili Islands have Hindu communities that also observe Nyepi to some extent, but Bali remains the primary island associated with this day of silence and spiritual observance. The key rituals involve a series of events including purification ceremonies, parades with effigies known as Ogoh-Ogoh, and a full day of silence observed island-wide. In summary, Nyepi is celebrated primarily on the island of Bali in Indonesia. Nearby islands with Hindu populations may also observe it but Bali is the central and most famous location for this celebration.
