World Time Zone Offset Calculator
Work out what time it is in another city given the time in yours.
Assumptions used in this calculation
- Standard time, no DST: Uses standard UTC offsets and doesn't automatically adjust for daylight saving time, check whether either location currently observes DST.
About this calculator
Scheduling a call, flight, or livestream across time zones means working out the time difference between two UTC offsets, which gets error-prone once you factor in half-hour offsets like India's UTC+5:30 or negative offsets in the Americas, and it's easy to add when you should subtract or vice versa. This calculator takes the hour in your city along with your UTC offset and the other city's UTC offset, then computes the equivalent local time in the other city by adding the difference between the two offsets to your time. It sidesteps the mental arithmetic of tracking positive and negative offsets and non-integer offsets like +5:30 or +9:45, though since it uses standard UTC offsets without automatically adjusting for daylight saving time, it's worth double-checking whether either location is currently observing DST before relying on the result for something time-sensitive.
Worked example
9 AM at UTC+0, other city UTC+5:30
Result: 2:30 PM
