Current time in London

London time zone

London alternates between Greenwich Mean Time and British Summer Time. The UK capital often bridges North American mornings and European afternoons, but U.S. and British clock-change dates do not always coincide.

The named time zone for London is Europe/London. For 2026, January 15 uses UTC+0 and July 15 uses UTC+1. These reference dates have different offsets, reflecting seasonal time rules. They are examples, not the exact transition dates. The live reading above uses your browser's time-zone data and your device clock.

When organizing a call to London, include the full calendar date and a named zone in the invitation. Check the converter for that date instead of adding a remembered number of hours: the other person's region may change clocks even when this destination does not. Overnight flights and late calls can arrive on a different local day. Keep London alongside other destinations in the world clock to compare today's readings; use the date-specific converter for future appointments.
