About Shanghai time
Shanghai runs on China Standard Time — the single zone used across the entire country, from the coast to the far west.
Remarkably, all of China — spanning roughly five geographic time zones — officially uses one clock set to Beijing/Shanghai time. In the far-western Xinjiang region this means the sun can rise near 10:00 by the official clock, and an unofficial local time runs two hours behind. Shanghai’s stock exchange and the week-long National Day and Spring Festival holidays strongly shape regional business hours.
