🌍 Time Zone Converter
Convert times between UTC, CET, CEST, EST, and other time zones instantly.
Time zone conversions trip up travelers, remote teams, and anyone scheduling across borders. A meeting set for 14:00 CET — what time is that for a colleague in New York, or for you in UTC? Our Time Zone Converter answers that instantly: pick your source time zone, enter a time, and see the equivalent in any target zone — UTC, CET, CEST, GMT, EST, EDT, IST, JST, and more — with daylight saving time handled automatically.
Here’s a practical example: your remote team in Amsterdam schedules a call at 10:00 CEST. Enter that in the converter with Europe/Amsterdam as the source, select UTC as the target, and you’ll see it’s 08:00 UTC. Or flip it — a US partner suggests a meeting at 09:00 EDT: set America/New_York as the source and Europe/Paris as the target to find the right moment for your European calendar.
This converter is especially valuable in spring and autumn. Because CEST (UTC+2) and CET (UTC+1) differ by an hour, a fixed “+1” assumption is wrong for half the year. Our tool reads the actual daylight saving time rules for every zone at the exact date you enter, so you never book across the DST switch by mistake.
All calculations run locally in your browser — no server calls, no tracking. Bookmark it for remote stand-ups, flight bookings, webinar times, or anything that crosses time zones.
Frequently Asked Questions
What's the difference between UTC, CET and CEST?
UTC (Coordinated Universal Time) is the world's time standard with no daylight saving. CET (Central European Time) is UTC+1 and is used in winter. CEST (Central European Summer Time) is UTC+2 and applies from the last Sunday of March to the last Sunday of October. Our converter applies these DST rules automatically based on the date you enter.
Is the converter daylight-saving aware?
Yes. Instead of using a fixed offset, the tool reads each zone's actual daylight saving time rules for the exact date you pick. So converting a date in January gives a different result from a date in July, exactly as it should.
What time zones are supported?
The tool covers UTC and the major world zones: Europe (London, Amsterdam, Paris, Berlin, Madrid, Istanbul), North America (New York, Chicago, Denver, Los Angeles, São Paulo), the Middle East (Dubai), and Asia-Pacific (Mumbai, Shanghai, Tokyo, Sydney).
How do I convert a meeting time across time zones?
Set the "From" zone to your local time, enter the meeting date and time, then set the "To" zone to your colleague's location. The result shows the equivalent time plus each zone's current UTC offset, so you can confirm it at a glance.
