Worked examples

While Toronto is UTC−5. An office that closes at 6:00 pm in India closes when it is 7:30 am in Toronto. A 9:00 am start in Toronto is 7:30 pm in India, and its 6:00 pm finish is 4:30 am the next day in India. A message sent at 10:30 pm from India lands at 12:00 pm in Toronto.

While Toronto is UTC−4. An office that closes at 6:00 pm in India closes when it is 8:30 am in Toronto. A 9:00 am start in Toronto is 6:30 pm in India, and its 6:00 pm finish is 3:30 am the next day in India. A message sent at 10:30 pm from India lands at 1:00 pm in Toronto.

When the date is different

Toronto is behind India (while Toronto is UTC−5), so for 10 hours 30 minutes of every day the calendar date differs: from midnight until 10:30 am India time, it is still the previous day in Toronto. Mention the date as well as the time when you fix something in those hours.

Toronto is behind India (while Toronto is UTC−4), so for 9 hours 30 minutes of every day the calendar date differs: from midnight until 9:30 am India time, it is still the previous day in Toronto. Mention the date as well as the time when you fix something in those hours.

Why the gap is what it is

Indian Standard Time follows the sun at longitude 82.5° east. The zone that Toronto belongs to has its largest city, Toronto, at about 79.4° west. The sun crosses the sky between those two lines in about 10 hours 48 minutes. Clock time rounds that to a tidy figure: 10 hours 30 minutes or 9 hours 30 minutes. The two figures differ because every country picks a round offset that suits its whole territory, and some add summer time on top.

Rows marked in colour fall between 8 am and 9 pm in both places. Dates are from the IANA time zone database 2026f.
