Time Difference: London to Beijing

Summary

See the current time in London and Beijing side by side, with the live UTC offset (CST is UTC+8 year-round), updated every second.

How it works

1. Your browser reads the current moment from your device clock.
2. It converts that moment to Europe/London time using the IANA timezone database built into modern browsers.
3. The same moment is converted to Asia/Shanghai time (CST, UTC+8), which Beijing follows.
4. The UTC offsets of both cities are compared to calculate the exact hour difference.
5. All three values — London time, Beijing time, and the offset — refresh every second.
6. When London switches between GMT and BST, the displayed offset adjusts automatically from +8 to +7 hours.
