About Time Zone Converter
Enter a date and time, pick a source time zone and a target time zone, and this converter reads your entered wall-clock time as if it were in the source zone and shows the matching moment in the target zone. It also lists each zone's UTC offset and the time difference between them.
It works with roughly two dozen common world zones and handles daylight saving time automatically. The tool is completely free, needs no sign-up, and runs entirely in your browser, so nothing you type is ever uploaded.
Frequently asked questions
- Is the time zone converter free to use?
- Yes, it is completely free with no account, sign-up, or limits. You can convert as many times between as many zones as you like.
- Is my data uploaded anywhere?
- No. Every calculation happens locally in your browser using the built-in Intl date API. Nothing you enter is sent to a server, stored, or tracked.
- How does it interpret the time I enter?
- The date and time you type is treated as the wall-clock time in the source zone you select. The tool then finds that exact moment and displays it in the target zone.
- Does it handle daylight saving time?
- Yes. It uses your browser's official time zone database, so daylight saving shifts and historical offset changes are applied automatically for the date you choose.
- Which time zones are supported?
- About two dozen common zones covering the Americas, Europe, Africa, the Middle East, Asia, and Oceania, including UTC, New York, London, Paris, Dubai, Mumbai, Shanghai, Tokyo, and Sydney.
- Can I quickly swap the two zones?
- Yes. Use the Swap zones button to reverse the source and target, and the Use current time button to fill in the current time in the source zone.
