Worked examples
While Paris is UTC+1. An office that closes at 6:00 pm in India closes when it is 1:30 pm in Paris. A 9:00 am start in Paris is 1:30 pm in India, and its 6:00 pm finish is 10:30 pm in India. A message sent at 10:30 pm from India lands at 6:00 pm in Paris.
While Paris is UTC+2. An office that closes at 6:00 pm in India closes when it is 2:30 pm in Paris. A 9:00 am start in Paris is 12:30 pm in India, and its 6:00 pm finish is 9:30 pm in India. A message sent at 10:30 pm from India lands at 7:00 pm in Paris.
When the date is different
Paris is behind India (while Paris is UTC+1), so for 4 hours 30 minutes of every day the calendar date differs: from midnight until 4:30 am India time, it is still the previous day in Paris. Mention the date as well as the time when you fix something in those hours.
Paris is behind India (while Paris is UTC+2), so for 3 hours 30 minutes of every day the calendar date differs: from midnight until 3:30 am India time, it is still the previous day in Paris. 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 Paris belongs to has its largest city, Paris, at about 2.4° east. The sun crosses the sky between those two lines in about 5 hours 21 minutes. Clock time rounds that to a tidy figure: 4 hours 30 minutes or 3 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.
