Time in Zhangjiagang, China

Time zone: CST (UTC/GMT +08:00) — Asia/Shanghai

The local standard in Zhangjiagang is CST — UTC+08:00, or 8 hours ahead of UTC. Systems that store time zones by name use Asia/Shanghai for this part of the world.

No seasonal adjustment applies in Zhangjiagang — UTC+08:00 is constant, which is worth remembering when a partner city moves its clocks twice a year.

Bear in mind China spans 2 zones across the 452 cities we cover — checking a second city in the same country is often necessary.

Zhangjiagang has roughly 1,432,044 residents and ranks 39th by population among the China cities on this site.

Current gap between Zhangjiagang and cities people most often need to coordinate with. These figures already account for daylight saving where it applies.

Assuming a 09:00–17:00 day at both ends, these windows (in Zhangjiagang local time) fall inside working hours for both cities.

No shared working window exists with New York, Los Angeles or Sao Paulo, so those calls have to sit outside somebody's normal hours.

Same zone, same time — each of these sits on Asia/Shanghai alongside Zhangjiagang, including through any clock change.
