Time difference between Delhi and Toronto

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 Toronto goes forward on the second Sunday in March and back on the first Sunday in November.

Delhi stays put all year while Toronto moves, so the gap changes twice a year from Toronto's side alone. A recurring meeting set in Delhi's calendar will drift by an hour without anyone touching it.

About Delhi and Toronto

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.

Toronto keeps the same clock as New York and changes on the same dates, so the two cities are never apart. Canada follows the US daylight-saving schedule rather than the European one, which is why Toronto and London drift for the same weeks New York and London do.

What 9 hours 30 minutes actually costs you

There is no shared working hour at all. Nine to five in Delhi is 11:30 PM to 7:30 AM in Toronto. Somebody has to be outside their working day, and the only question is who — so the useful thing is to decide that once rather than rediscover it every time.

The least painful slot is 5:00 PM in Delhi, which is 7:30 AM in Toronto. That is 1.5 hours outside somebody's working day and it is the smallest that gap gets — every other hour of the clock costs more.

At 9 hours 30 minutes the two are far enough apart that the date stops matching. Midday in Delhi is 2:30 AM the same day in Toronto, but the ends of the working day do cross. "Tomorrow morning" means different things to the two of you, and a deadline given without a date attached will be missed by one side or the other.

When they can both be at their desks

Nine-to-five in Delhi and nine-to-five in Toronto do not overlap at all. With 9 hours 30 minutes between them, one side is always outside working hours, and the practical question is which side takes the early start or the late finish rather than when to meet.

How far apart Delhi and Toronto are

The shortest path over the Earth's surface between the two is 11,633 km (7,228 miles). Flown along that line, an airliner at cruising speed takes roughly 14 hours 30 minutes in the air — actual routings add to it, and whether a nonstop service exists depends on the airlines rather than the distance.

Over that distance you cross 9 hours 30 minutes of clock, which is where jet lag comes from: the body shifts by about an hour a day, so 9 hours 30 minutes takes most people 10 days or so to absorb. Flying west to Toronto is the easier direction — you gain the hours, and staying up later comes more naturally than going to bed early.
