How the Time Zone Difference Calculator works
Destination time = your local time + (destination UTC offset − your UTC offset). Offsets can be fractional, such as 5.5 for India. Daylight saving time changes the offset, so enter the offset that applies on the travel date. Example: with Your local hour (0–23) 9, Minute 0, and Your UTC offset 7 h, the result is Time at destination = 21:00; Day = Previous day; Time difference (hours) = -12.
