About Timezone Converter

Offsets are resolved against the date you choose rather than stored as fixed numbers, so a meeting that lands the far side of a daylight-saving change shows the offset that will actually apply on the day, not today's.

Compare the time across several cities at once to find a meeting slot that works for everyone, with daylight saving handled automatically — a clean World Time Buddy alternative that runs in your browser.

Compare the current or a chosen time across multiple cities to plan calls, meetings and launches across the world, with daylight saving handled automatically. Add the zones you care about and see at a glance which slots fall inside everyone's working hours.

The converter uses the full IANA time-zone database, so offsets and daylight-saving rules match what the calendar will actually do on the day. Your selected zones are remembered, which makes it a quick, distraction-free alternative to World Time Buddy.

Frequently asked questions

How is this different from World Time Buddy?

The same core job — comparing times across cities to find a meeting slot — but it runs entirely in your browser with no account, no tracking and no usage limit. Your list of cities never leaves your device.

Is daylight saving handled automatically?

Yes. Conversions use the IANA timezone database via your browser, so DST transitions are applied per zone and per date — including the weeks when Europe and the US have already switched but the other has not.

Why does the offset change depending on the date?

Because DST rules differ by country and change over time. A city eight hours ahead in January may be nine in July, which is exactly why scheduling a recurring meeting across hemispheres drifts.

Pro Tips

→Add 5+ cities across timezones and see clock times update simultaneously to find optimal meeting times without math.
→Convert specific times/dates forward and backward across DST boundaries to catch scheduling conflicts before they happen.
→Use quick-add buttons for common zones (UTC, EST, PST, IST) to avoid typing long timezone names.
→Share calendar invite with converted times to ensure remote teams know exactly when the meeting happens in their local zone.

Common Use Cases

•Finding a meeting slot that works across several offices
•Checking what time it is for a colleague before calling
•Scheduling a launch or maintenance window across regions

How It Compares

Unlike world-clock.net which only shows current time, our converter includes historical DST rules and meeting planner matching, offering more accuracy than Google Calendar's basic timezone conversion and more user control than WorldTimeServer's simple lookup interface.
