What is the time difference between London and Shanghai?

Shanghai (CST, UTC+8) is 8 hours ahead of London in winter (GMT, UTC+0) and 7 hours ahead in summer (BST, UTC+1). China does not observe Daylight Saving Time, so the offset changes only when the UK shifts its clocks in spring and autumn.

Does Shanghai observe Daylight Saving Time?

No. China abolished DST in 1991 and has not used it since. Shanghai stays on CST (UTC+8) all year. Only London shifts its clocks, which is why the London-Shanghai gap alternates between 8 and 7 hours.

When does the offset change from 8 to 7 hours?

The UK moves clocks forward on the last Sunday in March at 01:00 GMT, entering BST (UTC+1). At that point Shanghai goes from 8 hours ahead to 7 hours ahead. The gap returns to 8 hours on the last Sunday in October at 02:00 BST when the UK reverts to GMT.

What are the best meeting times for London and Shanghai?

The overlap between standard business hours (09:00–18:00) is limited. When London is at 09:00 GMT it is 17:00 in Shanghai — late afternoon. A 09:00–10:00 London call (GMT) catches Shanghai at 17:00–18:00 CST, which is the most realistic overlap 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.

In China, CST stands for China Standard Time (UTC+8), used across all of mainland China year-round. There is no Daylight Saving Time in China, so the offset from UTC never changes.
