The gap is not the same all year
Every converter gives one number for this pair. That number is right for most of the year and wrong for part of it, because London goes forward on the last Sunday in March and back on the last Sunday in October and Delhi does not change its clocks.
| London / Delhi clocks | Difference | How long |
|---|---|---|
| summer / standard | 4 hours 30 minutes ahead | about 30 weeks |
| standard / standard | 5 hours 30 minutes ahead | about 22 weeks |
Delhi stays put all year while London moves, so a meeting fixed in Delhi's calendar shifts by an hour twice a year at London's end.
About London and Delhi
London is the reference the rest of the system is measured from: Greenwich sits inside the city, and UTC±0 is its winter time. It does not stay there — Britain moves to UTC+1 for seven months of the year, which is why "London is GMT" is wrong more often than it is right.
India runs a single zone at UTC+5:30 across nearly 30 degrees of longitude, so sunrise in the far northeast can be before five in the morning by the clock. Proposals to split the country in two have been made repeatedly and rejected each time.
What 4 hours 30 minutes actually costs you
The window is 3.5 hours wide and that is all there is. 9:00 AM–12:30 PM in London is 1:30 PM–5:00 PM in Delhi, and anything outside it puts somebody at their desk when they are not meant to be. A pair this tight is worth putting in a calendar rather than agreeing each time.
When they can both be at their desks
Nine-to-five in both cities overlaps for 3.5 hours — 9:00 AM to 12:30 PM in London, the same moment as 1:30 PM to 5:00 PM in Delhi.
How far apart London and Delhi are
The shortest path over the Earth's surface between the two is 6,711 km (4,170 miles). Flown along that line, an airliner at cruising speed takes roughly 8 hours 35 minutes in the air — actual routings add to it, and whether a nonstop service exists depends on the airlines rather than the distance.
A gap of 4 hours 30 minutes is small enough that most people adjust within a day or two, and short enough that it rarely disrupts a trip.
