When the difference changes
China Standard Time and British Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:
- Now – March 28, 2027British Time is 8 hours behind
- March 28, 2027 – October 31, 2027British Time is 7 hours behind
- October 31, 2027 – onwardsBritish Time is 8 hours behind
Periods shorter than a day are not listed. Each zone changes at its own local time, so on a date when both move there are a few hours when the gap is briefly something else.
Daylight saving
China Standard Time
China Standard Time stays on CST all year, so its offset from UTC never moves.
British Time
Clocks go forward one hour — 1:00 am becomes 2:00 am local time, and the zone is on BST after that.
