About this tool
Pick a date, time and source time zone to see the equivalent local time in other zones around the world, including the UTC offset for each. It is ideal for scheduling meetings and calls across regions.
Time-zone rules, including daylight saving time, come from your browser's built-in internationalisation data, so no external service is contacted.
Examples
- 09:00 in New York → 14:00 in London (during summer)
- Compare Tokyo, London and Los Angeles at a glance
- See the UTC offset for each selected zone
Frequently asked questions
Does it handle daylight saving time?
Yes. Conversions use your browser's time-zone database, which accounts for daylight saving transitions for each zone and date.
Which time zones are available?
A curated list of common zones is provided, covering major cities across every continent. Each is a standard IANA time zone.
Is an internet connection required?
No external API is used. Everything is computed locally from data already in your browser.
