CST – China Standard Time
UTC+08:00China Standard Time (CST) covers all of mainland China, 8 hours ahead of UTC.
- •China uses a single time zone despite spanning 5 geographical zones.
- •In Xinjiang (western China), sunset can be as late as midnight in summer.
- •China abolished daylight saving time in 1991.
- •The Shanghai Stock Exchange operates on CST/Beijing Time.
BST – British Summer Time
UTC+01:00British Summer Time (BST, UTC+01:00) is the daylight saving period in the United Kingdom, running from late March to late October.
- •BST runs from the last Sunday in March to the last Sunday in October.
- •BST is exactly one hour ahead of GMT, the UK's standard time.
- •During BST, London is 4 hours ahead of New York while the US is on Eastern Daylight Time.
- •The Isle of Man and the Channel Islands also observe BST.
Understanding the -7h Gap: China vs BST
China runs on China Standard Time (CST) at UTC+08:00. BST runs on British Summer Time (BST) at UTC+01:00. That puts China 7 hours behind BST — a difference of -7h at the current offsets.
In practice, when it is 9:00 AM in China it is 2:00 AM in BST. Midnight in China is 5:00 PM in BST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert China to BST time
- Scheduling a call from China to BST: a 10:00 AM start in China lands at 3:00 AM in BST, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both China and BST are inside the 9-to-5 working day between 4:00 PM and 5:00 PM CST time (9:00 AM–10:00 AM BST). That is roughly 1 hours of usable overlap.
- Watching a live event or market open: China viewers need 2:00 AM in BST to catch a 9:00 AM start there, and 7:00 AM if the event is anchored to China.
- Always state the zone abbreviation, not just the hour. "3:00 PM CST" is unambiguous; "3 PM" across a -7h gap is not.
- Block 4:00 PM–5:00 PM CST as the recurring meeting window if you work primarily from China and need BST colleagues present.
About CST (China Standard Time)
China Standard Time (CST, also known as Beijing Time) is used across all of mainland China despite the country spanning five geographical time zones. This single-timezone policy was adopted in 1949. China does not observe daylight saving time. CST is shared with Hong Kong (HKT), Macau, Taiwan, Singapore, Malaysia, and the Philippines, making UTC+08:00 one of the most used offsets in the world.
About BST (British Summer Time)
British Summer Time (BST) is the daylight saving period in the United Kingdom, when clocks move one hour forward from Greenwich Mean Time (GMT, UTC+00:00) to UTC+01:00. It runs from the last Sunday in March to the last Sunday in October. England, Scotland, Wales and Northern Ireland all follow it, along with the Isle of Man and the Channel Islands of Jersey and Guernsey. During BST, London is one hour ahead of UTC, four hours ahead of New York on Eastern Daylight Time, and five hours ahead of New York once the United States returns to Eastern Standard Time in November. BST is also used to abbreviate Bangladesh Standard Time (UTC+06:00), which is listed separately on this site.
Best time to call between China and BST
Both China and BST sit inside the 9 AM – 5 PM working day between 4:00 PM–5:00 PM CST, which is 9:00 AM–10:00 AM BST. That gives roughly 1 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
China and BST overlap for only 60 minutes (4:00 PM–5:00 PM CST), so meetings have to be booked precisely.
China is 7 hours behind BST (CST UTC+08:00 → BST UTC+01:00). The shared working window is 4:00 PM–5:00 PM CST. Remember to re-check around daylight-saving transitions.
