India time to London time

--:--
--:--

London is 4 hours 30 minutes behind India while the UK is on BST, from late March to late October. On GMT in winter, London is 5 hours 30 minutes behind.

Best overlap for calls and meetings

India and the UK share a solid part of the working day. In summer, London 9:00 to 13:30 equals India 13:30 to 18:00, which gives four and a half hours of overlap. In winter the shared slice shrinks to London 9:00 to 12:30, which is India 14:30 to 18:00. The London morning is the standard time for joint stand-ups, while the London afternoon reaches Indian staff after they have finished for the day.

Table worked out for 2026-10-15 with the real time-zone rules. When a daylight-saving change happens the gap shifts by an hour; the live clocks above always show the current difference.

The October and March shifts

The UK changes clocks on the last Sunday of March and October. On 25 October 2026 London returns to GMT and the gap grows from 4h30 to 5h30, so an 11:00 London call moves from 15:30 to 16:30 in India. On 28 March 2027 it shrinks again.

Flights from Delhi to London leave in the early afternoon and land the same afternoon in London, since the 9 to 10 hour flight gains back the time difference. Students in the UK often call home before 9:00 London time, when it is lunchtime in India.
