🌍 Time Zone Converter

About this Time Zone Converter

This time zone converter uses your browser's built-in time zone database (the same one your phone clock uses), so daylight-saving changes in London, New York, Sydney and elsewhere are handled automatically. Enter a meeting or flight time in one city and read it instantly in another, with the UTC time shown for reference.

How to use it

1. Pick the date and time (it starts at your current local time).
2. Choose the time zone that time is in, and the zone to convert to.
3. Click Convert time to see both times side by side.

Example

9:00 AM in Karachi is 5:00 AM the same day in London during British summer time, and 12:00 midnight in New York.

Frequently asked questions

Does it handle daylight saving time?

Yes — the conversion uses the real rules for the date you pick, so a January date and a July date in London convert differently, correctly.

Why can the day change?

Zones far apart sit on different calendar days: when it is morning in Sydney it is still the previous evening in Los Angeles.
