Time Zone Converter
Convert a specific date and local time between cities and IANA time zones. The browser applies the relevant UTC offset for that date, including daylight-saving changes where supported.
Convert meeting times without guessing the offset
A fixed “UTC+8 versus UTC−8” calculation can be wrong when one location changes for daylight saving time. This converter asks the browser for the offset that applies to the selected date in each named time zone, which is more useful for meetings, travel, live events and remote work.
How to use it
- Choose the date and local clock time in the source location.
- Select the source and destination time zones.
- Use Swap zones to reverse the conversion, or Use current time to start from now.
Privacy and accuracy
The conversion runs locally in your browser and does not need to upload the entered date or time. Time-zone rules can change by government decision, so results depend on the time-zone database shipped with your browser or operating system. For legal, aviation or other high-stakes scheduling, confirm against an authoritative source.
