Schedule a meeting across borders without guesswork. Pick the time that works for you, choose the other attendee's zone, and the tool shows their local time so you can confirm the slot before sending the invite.
How it works
Your proposed slot is interpreted as wall-clock time in your home zone, and Intl.DateTimeFormat converts it to the matching local time in the attendee's IANA zone for the exact date you chose. The quick-pick buttons swap the target zone instantly, so you can flip between New York, London, Berlin, Tokyo, and Sydney to find a slot that lands inside working hours for everyone involved before sending the invite.

Frequently asked questions
- How do I pick a good time for an international meeting?
- Start by entering your preferred meeting time in your local zone, then switch the target zone to each attendee's region. The tool reformats the time instantly so you can spot any zone where the slot falls outside working hours.
- Can I compare more than two zones?
- The tool compares one source zone with one target zone at a time. Use the quick city buttons to flip the target zone rapidly across major regions like New York, London, Berlin, Tokyo, Sydney, and Singapore.
- Does the planner respect daylight saving transitions?
- Yes. Because conversions use Intl.DateTimeFormat with the IANA database, the displayed time always reflects whether each zone is on standard or daylight saving time on the chosen date.
- What if my colleague's city is not in the dropdown?
- Pick the closest IANA zone in the same region. Cities that share a UTC offset and daylight saving rules show identical local times, so a nearby zone gives the same result.
