When NOT to use Time Zone Converter
- During the hour clocks jump forward or fall back, a local time can be skipped or occur twice — the result is the browser's best interpretation, so double-check critical meeting times.
- Don't use it for legal or aviation deadlines without confirming against an authoritative source for that zone.
Questions people ask
Does it handle daylight saving time?
Yes. The conversion uses your browser's built-in IANA time-zone database, so daylight saving time is applied automatically for the date you enter — for example, New York is UTC-5 in January and UTC-4 in July.
Which time zones are supported?
28 major zones: US zones (New York, Chicago, Denver, Los Angeles), Toronto, Vancouver, Mexico City, São Paulo, London, Paris, Berlin, Madrid, Moscow, Cairo, Lagos, Dubai, Karachi, Kolkata, Dhaka, Bangkok, Singapore, Shanghai, Hong Kong, Tokyo, Seoul, Sydney, Melbourne and Auckland — plus UTC.
Is my input sent anywhere?
No. All conversion math runs locally in your browser. Nothing is uploaded or stored.
