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 Delhi does not change its clocks and Sydney goes forward on the first Sunday in October and back on the first Sunday in April.
| Delhi / Sydney clocks | Difference | How long |
|---|---|---|
| standard / standard | 4 hours 30 minutes ahead | about 26 weeks |
| standard / summer | 5 hours 30 minutes ahead | about 26 weeks |
Delhi stays put all year while Sydney moves, so the gap changes twice a year from Sydney's side alone. A recurring meeting set in Delhi's calendar will drift by an hour without anyone touching it.
About Delhi and Sydney
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.
Sydney is UTC+10 in winter and UTC+11 from October to April. Its summer is the northern hemisphere's winter, so the gap to Europe and North America swings by two hours over the year rather than staying put.
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 Delhi is 1:30 PM–5:00 PM in Sydney, 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 Delhi, the same moment as 1:30 PM to 5:00 PM in Sydney.
How far apart Delhi and Sydney are
The shortest path over the Earth's surface between the two is 10,428 km (6,480 miles). Flown along that line, an airliner at cruising speed takes roughly 13 hours 5 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.
