Time and Calenda
Despite its size, China occupies only one time zone, and there is no daylight saving time. Midday in Beijing is also midday in far-flung parts of China, including Lhasa and Urumuqi, which are along the same latitude as countries that are two and three hours behind China. China time is 7 or 8 hours ahead of Greenwich Mean Time (GMT), 2 or 3 hours behind Australian Eastern Standard Time, 15 or 16 hours ahead of US Pacific Standard Time, and 12 or 13 hours ahead of US Eastern Standard Time. The Western Gregorian Calendar is used for all official work, although the lunar calendar(农历) is still used for calculation the dates of festivals.
