When the date is different

New York is behind India (while New York 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 New York. Mention the date as well as the time when you fix something in those hours.

New York is behind India (while New York 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 New York. 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 New York belongs to has its largest city, New York City, at about 74° west. The sun crosses the sky between those two lines in about 10 hours 26 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.
