Summary
This tool displays the live current time in both London (Europe/London — GMT in winter, BST in summer) and Shanghai (Asia/Shanghai — CST, UTC+8 year-round, no DST) side by side. Shanghai never observes Daylight Saving Time, so the offset between the two cities shifts twice a year: 8 hours ahead of London in winter (GMT) and 7 hours ahead in summer (BST). Use this tool to schedule calls with China, coordinate remote teams, or check whether Shanghai colleagues are still at work.
How it works
- Your browser reads the current moment from your device clock.
- It converts that moment to Europe/London time using the IANA timezone database built into modern browsers.
- The same moment is converted to Asia/Shanghai time (CST, UTC+8).
- The UTC offsets of both cities are compared to calculate the exact hour difference.
- All three values — London time, Shanghai time, and the offset — refresh every second.
- When London switches between GMT and BST, the displayed offset adjusts automatically from +8 to +7 hours.
Use cases
- Scheduling video calls between London and Shanghai offices.
- Checking if a colleague in Shanghai is still at their desk.

- Finding overlapping business hours for London-Shanghai meetings.
