Chinese New Year, otherwise known as the Spring Festival, is definitely not the time to travel around China, cross borders (especially the Hong Kong one) or be caught short of money.
Serf Emancipation Day was introduced as a public holiday in Tibet in 2009 to commemorate 50 years of Communist Chinese control in Tibet and what China says was the freeing of one million Tibetan ‘serfs’. Don’t expect much in the way of celebration among the ex-serfs.
Many Tibetan businesses, restaurants, shops and travel agencies are closed on the days of Losar and Saga Dawa. Tibetan festivals like these are held according to the Tibetan lunar calendar, which usually runs at least a month behind the Gregorian calendar. Ask around for the exact dates of religious festivals because monasteries often only fix these a few months in advance. Check Tibetan lunar dates against Gregorian dates at www.shambhala.com/tibetan-lunar-calendar.
China has several traditional and modern national holidays. They mean little to many Tibetans, but government offices and banks will be closed on many of these dates. Note that the length of holidays is subject to change.

The following are politically sensitive dates, as are 5 March, 27 September, 1 October and 10 December, which mark past political protests. It may be difficult for travellers to fly into Tibet for a few days before these dates. Tibet generally closes to foreign travellers for the entire month of March.
