Om det här verktyget
Pick a date, time and source time zone, then see the same instant in any number of other zones. Perfect for scheduling meetings across continents, planning a livestream so the right people are awake, coordinating a release window with a remote team, or figuring out when a flight actually lands in local time.
Uses the official IANA time zone database via your browser's Intl API, so daylight saving transitions and historical offsets are handled correctly - including the awkward cases like the half-hour offsets in India and Newfoundland, or the dates when a country changed its rules.
Because the conversion uses the database built into your browser, the results stay accurate even when you go offline. The catalog of zones it knows about is the same one used by Google Calendar, your operating system's clock, and every serious scheduling tool.
Funktioner
- Hundreds of IANA time zones (Europe/Copenhagen, America/Los_Angeles, Asia/Tokyo …)
- Add as many target zones as you need
- Daylight saving and historical rules handled automatically
- Defaults to your local zone for the source
- Half-hour and 45-minute offsets supported (India, Newfoundland, Nepal)
- Works offline once the page is loaded
Så använder du det
- Set a date and time, and pick the source zone (your local zone is selected by default).
- Add target zones from the dropdown - search by city or by zone name.
- Read the converted wall-clock time and date for each target.
- Copy any individual result with one click for pasting into a meeting invite.

Vanliga frågor
Yes. The Intl API uses the IANA tz database, which encodes DST rules and historical changes for every supported zone. Convert a date in March or November and you'll see the transitions reflected correctly.
Open the source zone dropdown - your current zone is detected from your browser and selected by default. If you're on a VPN that puts you in a different country, the detected zone may be wrong; pick manually if it matters.
Several countries have multiple zones (USA, Brazil, Russia, Australia). The IANA convention of Region/City picks a city in the right zone so the result is unambiguous - America/New_York and America/Los_Angeles are both in the USA but five hours apart in summer and three in winter.
Not yet. For now, set the time, take a screenshot, or paste the converted time into a meeting invite directly. Sharable timezone links are a candidate for a future update.
