Worked examples
While Los Angeles is UTC−8. An office that closes at 6:00 pm in India closes when it is 4:30 am in Los Angeles. A 9:00 am start in Los Angeles is 10:30 pm in India, and its 6:00 pm finish is 7:30 am the next day in India. A message sent at 10:30 pm from India lands at 9:00 am in Los Angeles.
While Los Angeles is UTC−7. An office that closes at 6:00 pm in India closes when it is 5:30 am in Los Angeles. A 9:00 am start in Los Angeles is 9:30 pm in India, and its 6:00 pm finish is 6:30 am the next day in India. A message sent at 10:30 pm from India lands at 10:00 am in Los Angeles.
When the date is different
Los Angeles is behind India (while Los Angeles is UTC−8), so for 13 hours 30 minutes of every day the calendar date differs: from midnight until 1:30 pm India time, it is still the previous day in Los Angeles. Mention the date as well as the time when you fix something in those hours.
Los Angeles is behind India (while Los Angeles is UTC−7), so for 12 hours 30 minutes of every day the calendar date differs: from midnight until 12:30 pm India time, it is still the previous day in Los Angeles. 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 Los Angeles belongs to has its largest city, Los Angeles, at about 118.2° west. The sun crosses the sky between those two lines in about 13 hours 23 minutes. Clock time rounds that to a tidy figure: 13 hours 30 minutes or 12 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.
