Loading today’s date…
Shanghai uses China Standard Time, known inside the country as Beijing Time: eight hours ahead of UTC, with no daylight saving. It is the only official time in China. Software nevertheless labels it Asia/Shanghai, because the time zone database names each zone after its most populous city, and Shanghai has more inhabitants than the capital. Hong Kong, Taipei, Singapore and Perth share the same offset.
China spans about 5,000 kilometres from east to west, the width of five time zones. The Republic of China defined five zones in 1912, from UTC+5:30 in the far west to UTC+8:30 in the north-east. Since 1949 the whole country has used a single time. Shanghai, on the east coast, sits comfortably within it. In Xinjiang, far to the west, many people informally keep “Xinjiang Time”, two hours behind, and shops there open correspondingly late by the official clock.
China tried daylight saving time from 1986 to 1991 and then dropped it; the clocks have not changed since. The Shanghai Stock Exchange trades from 09:30 to 11:30 and from 13:00 to 15:00. Its closing bell rings at 07:00 UTC, which is 07:00 or 08:00 in London depending on the season, before most European traders have started their day. Tokyo is one hour ahead of Shanghai all year.
