Every religion or culture all over the world has their own way to define and celebrate their new year.
The same thing also occurs in Bali, however the Balinese use many different calendar systems. They have adopted the Gregorian calendar for business and government purposes. But for the endless procession of holy days, temple anniversaries, celebrations, sacred dances, building houses, wedding ceremonies, death and cremation processes and other activities that define Balinese life, they have two calendar systems. The first is the Pawukon (from the word Wuku which means week) and Sasih (which is means month). Wuku consists of 30 items starting from Sinta, the first Wuku and end up with the Watugunung the last one. The Pawukon, a 210-day ritual calendar brought over from Java in the 14th century, is a complex cycle of numerological conjunctions that provides the basic schedule for ritual activities on Bali. Sasih, a parallel system of Indian origin, is a twelve month lunar calendar that starts with the vernal equinox and is equally important in determining when to pay respect to the Gods.
Westerners open the New Year in revelry, however, in contrast, the Balinese open their New Year in silence. This is called Nyepi Day, the Balinese day of Silence, which falls on the day following the dark moon of the spring equinox, and opens a new year of the Saka Hindu era which began in 78 A.D.
Nyepi is a day to make and keep the balance of nature. It is based on the story of when King Kaniska I of India was chosen in 78 A.D. The King was famous for his wisdom and tolerance for the Hinduism and Buddhism societies. In that age, Aji Saka did Dharma Yatra (the missionary tour to promote and spread Hinduism) to Indonesia and introduce the Saka year.
On Nyepi day itself, every street is quiet - there are nobody doing their normal daily activities. There is usually Pecalangs (traditional Balinese security man) who controls and checks for street security. Pecalang wear a black uniform and a Udeng or Destar (a Balinese traditional "hat" that is usually used in ceremony). The Pecalangs main task is not only to control the security of the street but also to stop any activities that disturb Nyepi. No traffic is allowed, not only cars but also people, who have to stay in their own houses. Light is kept to a minimum or not at all, the radio or TV is turned down and, of course, no one works. Even love making, this ultimate activity of all leisure times, is not supposed to take place, nor even attempted. The whole day is simply filled with the barking of a few dogs, the shrill of insect and is a simple long quiet day in the calendar of this otherwise hectic island. On Nyepi the world expected to be clean and everything starts anew, with Man showing his symbolic control over himself and the "force" of the World, hence the mandatory religious control.
