![]() ![]() Since the daylight hours are similar during every season, there is no advantage to moving clocks forward during the summer. Read more about sharing.Įquatorial and tropical countries (lower latitudes) generally do not observe Daylight Saving Time. If one is available, please include a link to the new law, or to news coverage of the new law. With your help, we can ensure that this exhibit is accurate. If there's been a change to the observance of Daylight Saving Time or Summer Time where you live, please let us know. Japan, India, and China are the only major industrialized countries that do not observe some form of daylight saving. Today, approximately 70 countries utilize Daylight Saving Time in at least a portion of the country. This map depicts countries that currently have DST, that previously had DST, and that never had DST. However, some regions in China such as the Xinjiang, Hong Kong, and Macau unofficially use different local time zones corresponding to their geographical locations.While the adoption of Daylight Saving Time is almost always rife with controversy, most of the world (except for countries around the Equator) has implemented DST at one point or another. ![]() The China Standard Time (CST) is the single time zone used in China and is referred to as Beijing Time in the country. The time offset of the region is UTC+08:00 for all the times throughout the year. ![]() The time system has lacked daylight savings since 1980. Macau also began using its system of time in 1999 after getting power. The original time system of this region adopted the astronomical observations but in 1904 it took the Greenwich Mean Time. The Hong Kong Time has lacked daylight savings since 1979. The area began using the Hong Kong Time (UTC+08:00) in 1997 following the transfer of sovereignty. Without the clarification, it will not be possible to distinguish between the two time zones.Īnother region using its time system is Hong Kong. As a result, inter-racial communication becomes difficult since the communicating parties must always clarify the time zones they are using every time they mention the time. The existence of two time zones in one geographical region is quite confusing to residents. Some of these nearby areas include the Kyrgyzstan and Kazakhstan. Moreover, the areas surrounding this area share the same time offset, the Xinjiang Time. The time setting used in this area is two hours behind the CST, and it corresponds to its geographical location, the furthest end of the western China. Areas such as Xinjiang use both the Beijing and Xinjiang Times simultaneously. Special Regulations of TimeĪfter the adoption of the Beijing Time, there are certain rules which govern the standard time system in some regions. There were two regions that did not adopt Beijing Time: the Community Party of Tibet and Xinjiang. The time offset that Beijing used was GMT+8. Later, in 1928, the time announcement changed to the traditional calendar of China.Īfter eleven years, the country shifted to the GMT+7 time offset which underwent a refined process leading to the adoption of the time system used in Beijing. The Beijing Local Mean Solar came into use in 1914. During that period, the official time announcement changed to GMT+8 while the universal time in China did not change until the year 1913. When the time announcement began in the 1880's, the Shanghai Mean Solar Time was used. China spans five time zones irrespective of the fact that it has single universal time offset. The time is officially referred to as Beijing Time with the feature of not having daylight saving since 1991. Its standard is UTC+08:00 which makes it ahead of the Coordinate Universal Time by eight hours. The time zone that China is currently using is the China Standard Time (CST). ![]()
