London runs 08:00 to 17:00 UK time and is the busiest session of the day. The clock below converts it to wherever you are, with daylight saving handled for you - which is where most published session tables go wrong.
The London forex session runs 08:00 to 17:00 UK time, Monday to Friday: 08:00-17:00 UTC in winter and 07:00-16:00 during British Summer Time. It is the largest session by volume, which usually means tighter spreads and wider ranges, and it overlaps New York from the US open until the London close. The clock here converts it to your own zone.

Sessions shown as each city's normal business hours (Sydney 7:00–16:00, Tokyo 9:00–18:00, London 8:00–17:00, New York 8:00–17:00 local), converted to your time zone with daylight-saving handled automatically. Forex trades 24 hours from Sunday evening to Friday evening (New York time); the London–New York overlap is usually the most active window.

The clock above uses your device's time zone and the real daylight-saving rules for each city.
London sits between the Asian close and the US open, and it is the largest FX trading centre by volume. In practice that means tighter spreads, larger ranges and more follow-through than the Asian session, especially in the first hours after the open.
