How to Convert Time Between Time Zones
Formula
Working across time zones is a daily reality for international businesses, remote teams, travelers, and anyone communicating globally. Converting time between zones requires knowing the UTC offset of both the source and target locations. This calculator makes the conversion simple: enter your current time, your local UTC offset, and the target UTC offset to see the equivalent time in the other zone, including whether the date changes.
The calculation adds the difference between the two UTC offsets to the source time. Some time zones have half-hour or quarter-hour offsets (such as India at UTC+5:30 or Nepal at UTC+5:45), which this calculator supports via decimal offset values. The result is wrapped to a 24-hour format, and a day-offset indicator tells you if the converted time falls on the previous or next calendar day.
Common use cases:
- Scheduling international meetings across time zones
- Coordinating global team stand-ups and handoffs
- Planning international travel and flight arrivals
