When it is 09:00 in New Delhi it is 03:30 in London in January and 04:30 in July. London is 5 hours 30 minutes behind New Delhi right now — but it is not constant: the difference is 5 hours 30 minutes behind in January and 4 hours 30 minutes behind in July. This page gives the live times in both cities, the overlap between their working days, the daylight saving dates that move the difference, and the best meeting windows.

Live times in New Delhi and London
The two cities side by side. The January column uses the winter offsets (New Delhi UTC+05:30, London UTC+00:00); the July column uses the summer offsets (New Delhi UTC+05:30, London UTC+01:00).

The world clock shows the current time in both cities live, and the individual city pages — time in New Delhi and time in London — explain each city's time zone, offsets and daylight saving in full.
The time difference between New Delhi and London
The difference is not constant. In January London is 5 hours 30 minutes behind New Delhi; in July it is 4 hours 30 minutes behind New Delhi. The difference changes on Sunday, 29 March 2026 (from 5 hours 30 minutes behind to 4 hours 30 minutes behind) and Sunday, 25 October 2026 (from 4 hours 30 minutes behind to 5 hours 30 minutes behind) — those are the dates when one of the two cities changes its clocks and the other does not, or when they change on different days. Between those dates the difference is one value; outside them it is the other.
To convert a time, add the difference: 09:00 in New Delhi is 03:30 in London in January and 04:30 in July; 17:00 in New Delhi — the end of the working day — is 11:30 in London in January and 12:30 in July. To go the other way, subtract it: 09:00 in London is 14:30 in New Delhi in January. The time difference calculator does the arithmetic for any date, and the UTC to London page gives the full conversion table for London.
Meeting overlap between New Delhi and London
The overlap is the hours when both cities are in their working day (09:00–17:00 local time). The table marks the overlapping hours in New Delhi's working day and shows what time they are in London.

| New Delhi time | London time | Both working? |
|---|---|---|
| 09:00 | 04:30 | No |
| 10:00 | 05:30 | No |
| 11:00 | 06:30 | No |

In January the overlap is 2 hours: 09:00, 10:00 New Delhi time. In July it is 2 hours: 15:00, 16:00 New Delhi time. The meeting planner finds the overlap for any two cities and any date, and the meeting time finder finds it for a whole team.
Daylight saving in New Delhi and London
New Delhi does not observe daylight saving, so its offset of UTC+05:30 never changes.
London observes daylight saving: in 2026 the clocks go forward on 29 March 2026 and back on 25 October 2026, moving the offset from UTC+00:00 to UTC+01:00.
The difference changes on Sunday, 29 March 2026 and Sunday, 25 October 2026 in 2026. On those dates, one city changes its clocks and the other does not — or they change on different days — so the difference moves by an hour. A standing meeting set in one city's local time will land an hour early or late on the other side until the second city catches up. The fix is to set the calendar event in UTC, or to check the overlap again after each change. The individual DST pages — New Delhi DST 2026 and London DST 2026 — give the exact dates for each city.
Best meeting windows
The best windows in January are 09:00–11:00 in New Delhi (03:30–05:30 in London). These are the hours inside both working days, so nobody is up early or late. It is a short window, so keep the meeting short and send an agenda in advance.
In July the best windows are 15:00–17:00 in New Delhi (10:30–12:30 in London) — the same logic, with the July offsets.
Calling and travel notes
When it is 09:00 in New Delhi it is 03:30 in London in January; when it is 12:00 in New Delhi it is 06:30 in London; when it is 17:00 in New Delhi it is 11:30 in London. The difference is under 12 hours, so the two cities are usually on the same date — but check the date for late-evening and early-morning times, when the date can differ by a day. Scheduling between Asia and Europe works best in the late morning in London and the afternoon or evening in New Delhi. The difference is 5–9 hours, so the overlap is a few hours in the middle of the day. The main trap is daylight saving: Europe changes its clocks twice a year, and most of Asia does not, so the difference — and the overlap — moves by an hour in March and October.

The table is the whole pair in one place. The two numbers that matter most are the January and July offsets: if they are the same in both columns for a city, that city's offset never changes; if they differ, the city observes daylight saving and the difference between the cities moves with it. The individual city pages — time in New Delhi and time in London — explain each city's time zone, and the DST pages — New Delhi DST 2026 and London DST 2026 — give the exact change dates.
