Meeting planner — find when everyone is awake
Add each participant's city, then click a column. Green = business hours, yellow = awake, grey = asleep. ★ marks the best overlap.
Plan across time zones
Whether you are scheduling a call, catching a livestream or booking travel, set the time in one place and read it instantly in another. Daylight saving is resolved with your browser's installed Intl/IANA data for the exact date you choose. The meeting planner paints each real hour side by side — including 23- and 25-hour transition days — for up to eight cities.
FAQ
Does it handle daylight saving time?
Yes. It uses the Intl/IANA time-zone data installed with your browser or operating system. Updates depend on that software, so the tool does not claim its database is always the latest.
What happens to skipped or repeated clock times?
A skipped time is rejected as nonexistent. A repeated time shows both UTC offsets and asks you to choose the first or second occurrence.
Which time zones can I choose?
All IANA time zones your browser supports — hundreds of cities and regions worldwide.
How do I convert a meeting time?
Set the date and time in the source zone, choose the target zone, and the converted local time appears instantly.
How does the meeting planner work?
Add every participant’s city and read the reference city’s real civil-day strip (23, 24 or 25 hours): green = business hours, yellow = awake, grey = night. Click a column to pick that exact moment; the best-overlap columns are starred.
Does the planner get the date right across the international date line?
Yes. Each city shows a −1d/+1d badge when its local date differs from the reference city, so an Auckland-morning call correctly shows as the previous afternoon in Los Angeles.
What is in the .ics download?
A standard calendar event at the selected moment (in UTC, so every calendar app converts it correctly), with all cities’ local times listed in the description. It imports into Google Calendar, Outlook and Apple Calendar.
