Calculating the live gap…
Two financial centers, most of a working day apart
Shanghai and London anchor Asia's and Europe's largest financial markets, and their trading days barely touch. The Shanghai Stock Exchange runs 9:30 a.m. to 3:00 p.m. local with a lunch break; the London Stock Exchange runs 8:00 a.m. to 4:30 p.m. local. With a seven-to-eight-hour gap between them, Shanghai's trading day has already closed by the time London opens \u2014 so any coordination between the two, financial or otherwise, is usually squeezed into a narrow morning-London / afternoon-Shanghai window, or handled asynchronously.
Why the gap changes twice a year
Since Shanghai never moves its own clock, the only two moments the Shanghai-London gap ever changes are the two dates London's clock changes \u2014 both set by UK law, not by any coordination with China.
Both dates above are calculated live from the actual UK clock-change rule for this year, so they stay correct automatically without anyone updating this page.
Best time to call, hour by hour
The table below runs through a full Shanghai day and shows the matching London time for each hour, with the rows where both cities fall inside a typical 9:00–17:00 workday highlighted — there usually aren't many.

Where the table shows no overlap, the practical workaround most teams use is a Shanghai late-afternoon call meeting a London mid-morning slot, or handling things asynchronously overnight.
How we calculate this page: both live clocks, the current gap, the DST transition date, and the hour-by-hour overlap table are all computed directly from the IANA Asia/Shanghai and Europe/London time zone data via your browser on every page load.
Frequently asked questions
What is the time difference between Shanghai and London right now?
Eight hours during UK winter time (GMT, roughly late October to late March) and seven hours during UK summer time (BST, roughly late March to late October). Shanghai never shifts its own clock, so the entire change comes from London.
Why does the Shanghai-London gap change if Shanghai never shifts its clock?
Because London does. The United Kingdom moves clocks forward on the last Sunday of March and back on the last Sunday of October. China abolished daylight saving time in 1991 and has kept a single fixed UTC+8 nationwide ever since, so those two UK transition dates are the only moments the Shanghai-London gap ever changes.
What is the best time to schedule a call between Shanghai and London?
Roughly 8:00–10:00 a.m. in London overlaps with mid-to-late afternoon in Shanghai, giving both cities a couple of hours inside a normal workday. Outside that window, one side is typically asleep.
Is Shanghai ahead of or behind London?
Shanghai is always ahead of London — by seven to eight hours, depending on the time of year.
How do I convert Shanghai time to London time?
Subtract seven hours during UK summer time (BST) or eight hours during UK winter time (GMT). For a guaranteed-accurate conversion on any specific date, use the time zone converter on WatchTime Online.
