Frequently asked questions
Does it handle daylight saving time?
Yes. Conversions use your browser's built-in time zone database, which applies each zone's current DST rules for the exact date you enter — including historical and future rule changes.
What if my city isn't in the list?
The list covers the world's major zones. Pick the closest major city in the same zone — e.g. Paris covers all of Central Europe, Singapore covers much of Southeast Asia.
Why do some conversions shift the date?
Time zones span the globe, so a morning meeting in New York is already evening in Tokyo. The result always shows the correct local date alongside the time.
Is my input sent anywhere?
No. All calculations happen in your browser. Nothing you enter ever leaves your device.
How accurate is this?
As accurate as your device's time zone data, which updates with your operating system. For critical scheduling, double-check against your calendar app.
