Frequently Asked Questions

What is the time difference between Bangalore and London?
During GMT (standard time), London is 5.5h behind IST. During BST (daylight saving), the difference becomes 4.5h. The live clock on this page always shows the correct current time.
When do clocks change in London and how does it affect IST?
UK clocks go forward 1 hour at 1 AM on the last Sunday in March (BST) and back at 2 AM on the last Sunday in October (GMT).

During BST (late Mar–late Oct) London is only 4h 30m behind IST instead of 5h 30m. Indian offices often schedule London calls at 1:30 PM IST (9 AM BST in summer, but 8 AM GMT in winter — important for early-morning London meetings).
What is 9 AM IST in London?
9:00 AM IST (Bangalore) = 3:30 AM GMT (or 4:30 AM BST during summer) in London.
What is the best time to schedule a meeting between Bangalore and London?
The optimal meeting window is 2:30 PM–6:00 PM IST when both Bangalore and London offices are open. Book in this window to avoid after-hours calls. Note: optimal windows shift by 1 hour when London changes clocks — update your recurring calendar invite each spring and autumn.
Does India observe daylight saving time (DST)?
No. India (IST, UTC+5:30) does not observe daylight saving time and has not done so since 1945. Indian Standard Time is fixed year-round. This means that when London changes its clocks in spring or autumn, the gap between Bangalore and London changes — but Bangalore stays fixed.
Why is India on a half-hour timezone (UTC+5:30)?
India's UTC+5:30 offset was established in 1905 as a compromise between the time zones of Bombay (UTC+4:52) and Calcutta (UTC+5:54) when India unified under British rule. Several countries use half-hour or quarter-hour offsets — including Nepal (UTC+5:45), Iran (UTC+3:30), and parts of Australia (UTC+9:30) — to better align solar noon with clock noon across their territory.
