What is the time difference between Tokyo and Shanghai?

Tokyo (JST, UTC+9) is always 1 hour ahead of Shanghai (CST, UTC+8). Neither country observes Daylight Saving Time, so this gap never changes throughout the year.

Does Tokyo observe Daylight Saving Time?

No. Japan abolished DST in 1952 and has not used it since. Tokyo stays on JST (UTC+9) all year.

Does Shanghai observe Daylight Saving Time?

No. China standardized on CST (UTC+8) in 1991 and has not observed DST since. The 1-hour gap between Tokyo and Shanghai is fixed and permanent.

What are the best meeting times when calling from Tokyo to Shanghai?

Because the offset is only 1 hour, the standard business hours (09:00–18:00) overlap almost entirely. Tokyo 09:00–18:00 corresponds to Shanghai 08:00–17:00. Any hour between 09:00 and 17:00 JST is a solid meeting window.

Is this tool accurate for scheduling?

Yes. It uses the IANA timezone database embedded in your browser — the same source used by operating systems and calendar apps worldwide. Accuracy depends on your device clock being synchronized via NTP, which most devices do automatically.

What is CST in the context of Shanghai?

CST here stands for China Standard Time, which is UTC+8. It is used across mainland China year-round. Note that CST is also an abbreviation for Central Standard Time (UTC-6) in North America — context determines which is meant.
