Compare multiple global cities simultaneously on an interactive 24-hour slider to find comfortable overlapping working hours.
Scheduling calls across New York, London, Tokyo, and Sydney is tricky because it is easy to accidentally book a meeting in the middle of a colleague's night. A visual time slider shows working hours and sleeping hours side-by-side so you can pick a respectful time for everyone.
Worked example: Find an overlapping meeting time between New York and London
Input
Comparing New York (EST) and London (GMT).
Expected result
A window between 9:00 AM–12:00 PM in New York corresponds to 2:00 PM–5:00 PM in London.
Both participants are within normal business hours without anyone needing to wake up early or stay past dinner.
Before you use the result
- Double-check daylight saving time changes, which happen on different weekends in spring and autumn.
- Look for the gold highlight indicator representing business working hours (9 AM to 5 PM).
- Send calendar invitations with time zone data included so recipients' phones automatically adjust.
If the result is not what you expected
A colleague's local time was one hour off.
One country may have shifted for daylight saving time while the other has not yet changed. Always check the date of the scheduled call.
