What CST (China) and BST Actually Are
CST (China) — China Standard Time
Shanghai, Beijing, Shenzhen, Guangzhou, Chengdu. Standing at UTC+8:00 as written, and the region does not change its clocks, so that offset holds all year. Written CST, the same letters as US Central Standard Time (UTC-6) — a genuinely common source of missed meetings. All of China runs on this single zone despite spanning five geographic ones.
China spans five geographic time zones but runs on one clock, set to Beijing. In Xinjiang, at the far west, many residents informally keep a local time two hours behind the official one.
BST — British Summer Time
London, Manchester, Birmingham, Glasgow, and the rest of the UK from late March to late October. Standing at UTC+1:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, October 25, 2026, to GMT. BST also stands for Bangladesh Standard Time (UTC+6). BDT is the clearer label for that one.
British Summer Time began in 1916 as a wartime fuel-saving measure and has run every year since, making it one of the oldest continuous daylight saving schemes in the world.
What This Means in Practice
This gap is not fixed
BST changes its clocks and CST (China) does not, so the difference between them moves by an hour twice a year. A recurring meeting set now will drift for one side from Sunday, October 25, 2026 unless someone resets it.
