About Timezone Converter
The Timezone Converter takes a date and time in one timezone and instantly shows the matching local time in another, covering major cities across the Americas, Europe, Africa, Asia, and the Pacific. It is a quick way to schedule meetings, calls, and live events across regions without doing the math by hand.
Conversions are calculated in your browser using built-in international time handling, so daylight saving shifts are taken into account automatically. Pick a source zone, choose a target zone, and copy the result with a single click for emails, invites, or calendars.

Frequently Asked Questions
Does the converter handle daylight saving time?
Yes. It uses your browser's built-in international time data, which applies the correct daylight saving rules for each timezone and date you enter.
Which timezones are supported?
The tool includes a curated list of major zones such as UTC, New York, Los Angeles, London, Paris, Dubai, Kolkata, Shanghai, Tokyo, Sydney, and more, spanning every major region.
Why does it default to a particular source timezone?
The converter tries to detect your device's local timezone and selects it as the source so you can convert from your own time without changing anything.
Is my entered time uploaded anywhere?
No. All conversion happens locally in your browser, so the date and time you enter never leave your device.
