Set a time in your zone and instantly see what it is in any city worldwide — perfect for scheduling calls and meetings.
The world is divided into roughly 24 time zones, each generally offset from Coordinated Universal Time (UTC) by a set number of hours. Some countries use half-hour or 45-minute offsets, and many regions shift their clocks for Daylight Saving Time during part of the year.
Daylight Saving Time changes don't happen on the same dates everywhere, and some countries don't observe it at all. This means the time difference between two cities can shift by an hour at different points in the year, which is why this converter calculates live using each city's actual time zone rules rather than a fixed offset.
When scheduling across time zones, look for hours where both locations fall within a typical 9am–6pm workday. Teams spread across more than 8–9 hours of time difference often need to rotate meeting times fairly, since a perfect overlap may not exist.
Yes. This converter uses your browser's built-in time zone database, which automatically applies the correct Daylight Saving Time rules for the date you select in each location.
UTC (Coordinated Universal Time) is the modern time standard used worldwide. GMT (Greenwich Mean Time) is technically a time zone rather than a standard, but in practice the two are treated as equivalent for most everyday purposes.
Some regions, including India, parts of Australia, and Iran, use 30 or 45-minute offsets from UTC rather than a full hour, which can make the difference between two cities a non-whole number.
