Time Zone Converter
One time, every time zone — plus the best meeting window inside everyone's working hours.
Private by design: everything runs in your browser. Nothing is uploaded.
How it works
- Set your time zone, date and time — and pick 2 to 6 zones to compare.
- Hit Convert to see the same moment in every zone.
- Check the "Best meeting window" hint for hours inside everyone's 9-to-5.
FAQ
Are daylight-saving changes handled?
Yes. Offsets are computed for the exact date you enter, so DST transitions are reflected automatically.
What is the "best meeting window"?
The hours of the day (shown in your time) when every selected zone is inside its local 9:00–17:00 working hours.
Can I add a time zone that isn't listed?
Yes — type any IANA name (e.g. Pacific/Auckland) and hit Add. The name must be spelled exactly right.
