Time and Calendar
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 Urumqi, which are along the same latitude as countries that are two and three hours behind China. China time is seven or eight hours ahead of Greenwich Mean Time (GMT), two or three hour behind Australian Eastern Standard Time, and 12 or 13 hours ahead of US Eastern Standard Time. Calendar is used for all official work, although the lunar calendar is still used for calculating the dates of festivals.
