UK Time Zones Overview

Summary

The United Kingdom and its Crown Dependencies share a single time zone (GMT/BST), while overseas territories like Gibraltar differ. Great Britain and Northern Ireland follow GMT in winter and British Summer Time (BST, UTC+1) in summer. The Crown Dependencies — Jersey, Guernsey, and the Isle of Man — keep the same offset as mainland UK. The British Overseas Territory of Gibraltar also aligns with Central European Time. This tool shows a live, auto-refreshing clock for every region so you always know the current local time.

How it works

1. The tool reads your browser's system clock every second.
2. Each region's UTC offset is calculated using the IANA time zone database built into modern browsers.
3. DST transitions are detected automatically — no manual updates needed.
4. The current UTC offset and DST status are displayed alongside each clock.
5. Click "Copy time" on any card to copy that region's time to your clipboard.
