Time Difference: London to Riyadh

Summary

See the current time in London and Riyadh side by side, with the live UTC offset (AST is UTC+3, no DST), 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/Riyadh time (AST, UTC+3).
4. The UTC offsets of both cities are compared to calculate the exact hour difference.
5. All three values — London time, Riyadh time, and the offset — refresh every second.
6. When London switches between GMT and BST, the displayed offset adjusts automatically from +3 to +2 hours.
