London uses Greenwich Mean Time (GMT, UTC+0) and moves to British Summer Time (BST, UTC+1) for part of the year. As the home of the Prime Meridian, it is the reference point for the world's time zones.
Clocks spring forward on the last Sunday of March and fall back on the last Sunday of October.
The London Stock Exchange trades from 8:00 AM to 4:30 PM GMT/BST. London sits between Asian and American markets, so its trading hours overlap with both.
