Nyepi, the Day of Silence, marks the Balinese Saka new year with twenty four hours of enforced stillness across the island: no work, no travel, no fire or light, and no entertainment, observed from six in the morning until six the following morning, with even the island's international airport closed for the day, a near total suspension of ordinary life found in few other religious observances anywhere. Residents remain indoors, refrain from cooking, and keep noise and light to a minimum, and tourists, regardless of their own religion, are asked to observe the same restrictions and stay within their hotels for the duration.
The silence is understood to persuade malevolent spirits that Bali is uninhabited, prompting them to pass over the island and leave it undisturbed for the coming year, while giving Balinese Hindus themselves a day set aside for fasting, meditation and self reflection at the year's turning point. Fred Eiseman's study of Balinese religion situates Nyepi within the island's wider calendar of purification rites, in which the visible ceremonial world, sekala, and the unseen spiritual world, niskala, are understood to require regular, deliberate rebalancing through ritual action.
The eve of Nyepi brings the opposite of the following day's silence: villages parade and then ceremonially burn ogoh-ogoh, towering effigies of demonic spirits built from bamboo, wood and papier-mache, accompanied by gamelan music and large public gatherings, a noisy ritual expulsion of negative forces that the following day's total silence is then understood to seal in place.
