Live clocks for London and Delhi, the exact difference as it stands today, a converter preset to this pair, and the full 24-hour comparison table — daylight saving handled on both sides.
Converting from London time
The full day in London on today, with the matching time in Delhi:
| London | Delhi |
|---|
Both clocks above are read live from the IANA time-zone database built into your browser — the same rule set your phone uses. “Difference today” is not a fixed fact about this pair of cities: it is computed from the two zones’ offsets right now, which is why it can legitimately read differently if you open this page in a different month.
The difference between London and Delhi swings with the seasons: in January Delhi is 5 hours 30 minutes ahead of London, and in July it is 4 hours 30 minutes ahead. London moves its clocks for daylight saving while Delhi stays on the same offset all year.
The 24-hour table walks the whole of today in London, hour by hour, and prints the matching moment in Delhi — including the rows where Delhi is still on yesterday, or already on tomorrow, which are marked +1 day or −1 day. Those edge rows are exactly the ones people get wrong doing the maths in their head.
Convert any moment between 44 world time zones, with offsets and DST handled.

2:30 PM — that is 9:00 AM in London converted on a January day, when London is at UTC+0 and Delhi is at UTC+5:30. Check it any time with the converter above: the answer is worked out from the two zones’ offsets on the date you pick, so it stays right when the clocks change.
Yes — the difference changes during the year, on the clock-change dates. The difference between London and Delhi swings with the seasons: in January Delhi is 5 hours 30 minutes ahead of London, and in July it is 4 hours 30 minutes ahead. London moves its clocks for daylight saving while Delhi stays on the same offset all year.
There is a comfortable overlap between the two working days: 9:00 AM–12:30 PM in London is 1:30 PM–5:00 PM in Delhi — inside both cities’ 9-to-5, so calls in that window suit both sides.
From timestamps and the IANA time-zone database inside your browser — the live rules for each zone, including daylight-saving start and end dates and southern-hemisphere seasons where relevant. Nothing is hard-coded: open this page on a clock-change day and the clocks, the difference and the 24-hour table all follow the new offsets automatically.
Two offsets and one subtraction — the same method the converter at the top of this page runs:
Take 9:00 AM in London, on a January day, when London is at UTC+0 and Delhi is at UTC+5:30. Adding the pair’s difference for that date gives 2:30 PM in Delhi. The subtlety is that the difference itself is date-dependent for this pair: repeat the same conversion in a month when one city has changed its clocks and the answer can move by an hour. That is why this page never prints a single fixed “the difference is X” without the word today next to it.
