Best meeting time between UK and India
The UK-India pair is one of the friendliest in global business. India is 4.5 or 5.5 hours ahead of the UK (depending on British Summer Time), which leaves a wide overlap of working hours every day. If your team is split between London and Bengaluru, Mumbai or Delhi, you can almost always find a slot that works for both sides without anyone starting early or staying late.
Why this pairing works so well
India Standard Time is set at UTC+5:30 because India operates on a single nationwide time zone, despite the country spanning roughly 30 degrees of longitude. The half-hour offset can feel awkward at first, but it actually makes the overlap with the UK more generous than any neighbouring whole-hour zone would. The UK shifts twice a year to BST, but Indian clocks stay still.
| Period (approx.) | UK | India | Difference |
|---|---|---|---|
| Late Mar – late Oct | BST (UTC+1) | IST (UTC+5:30) | 4.5 hours |
| Late Oct – late Mar | GMT (UTC+0) | IST (UTC+5:30) | 5.5 hours |
The classic London-Bengaluru window
For most teams, the sweet spot is the London afternoon vs. the India evening, or equivalently the India late afternoon vs. the London morning. Both sides cover roughly 13:30–18:00 IST ↔ 08:00–13:30 UK time as a fully overlapping working block, where everyone is awake, caffeinated and on the clock.
| UK time (BST) | India time (IST) | Verdict |
|---|---|---|
| 08:00 | 12:30 | Easy — UK fresh start, India lunch |
| 10:00 | 14:30 | Best mutual window |
| 12:00 | 16:30 | Best mutual window |
| 14:00 | 18:30 | Edge of India working day |
| 16:00 | 20:30 | Late for India |
Recurring meetings: pick a UK time, not a UTC offset
Because the UK shifts in and out of BST twice a year, a meeting pinned to a fixed UTC offset will drift relative to UK office hours. The simplest rule is to anchor recurring meetings to UK local time. India will see the meeting move by an hour twice a year, but it will still hit the same UK working slot — which is what most teams care about. If India hosts the meeting, anchor on IST and let the UK side accept the seasonal shift.
Operational use cases
- Daily stand-ups: 13:00 IST is 08:30 BST — a clean, energetic morning for the UK and an after-lunch return for India.
- Quarterly reviews: Anchor on a UK 11:00 start so London, Edinburgh and India can attend without flexing.
- Out-of-hours support: India 09:00–13:00 IST gives coverage during the early UK morning, useful for incident response.
Holidays to plan around
India observes a handful of public holidays that the UK does not (Diwali, Holi, Independence Day, regional festivals). The UK has its own pattern (early May, late May and August bank holidays, plus Christmas/Boxing Day). When scheduling quarterly all-hands or release windows, lay both calendars side by side — otherwise you will inevitably find one team off the clock.
FAQ
Does India use daylight saving time?
No. India Standard Time stays at UTC+5:30 all year.
Are Bengaluru, Mumbai, Delhi and Chennai on the same time?
Yes. India runs a single national time zone, so all major cities share IST.
What's the easiest meeting time for a London-Bengaluru team?
10:00–13:00 UK time. That's 14:30–17:30 in India during BST, or 15:30–18:30 during GMT — comfortable both sides.
