Balinese festival

Apart from the usual western calendar, the Balinese also use two local calendars, the Hindu saka and the wuku. The wuku calendar, which is used to determine festival dates, uses 10 different types of weeks between one and 10 days long, all running simultaneously! The intersection of the various weeks determines auspicious days. It's impossible to work it out yourself: when you arrive in Bali, try to get close contact to Balinese people and ask which festivals and celebrations are coming up.
