Meeting planner
The first zone is the reference row; hours across the top are its hours. Click an hour to pick a slot.
A meeting time works across zones when the same instant falls inside everyone’s working day. Add the zones above and the grid shows all 24 hours of the reference zone, colour-coded for each participant, with the hours that suit everyone highlighted. Pick one and export a calendar invite that lands at the right local time for each person.
How this is calculated
Each hour of the reference zone on the chosen date is converted to an absolute instant and rendered in every other zone — so the grid is correct on days when some zones have changed their clocks and others have not. Cells are classified against the working-hours range you set: inside it, within two hours before or three after (early/late), or night.
The calendar file is a single RFC 5545 event with the start in UTC; calendar apps translate it to each attendee’s local time. The event carries a link back to this page with the same zones, so it can be re-opened.

Frequently asked questions
How do I find a meeting time that works across time zones?
Line the zones up hour by hour for the date, mark which hours fall inside each person’s working day, and look for a column where every row is inside it. The grid above does that: green is inside working hours, grey is early or late, plain is night.
What if no hour works for everyone?
The planner then shows the hours that are merely early or late for someone rather than the middle of the night. Between New York and Tokyo, for example, there is no shared working hour at all — someone is always outside 9 to 5.
Why does the planner ask for a date?
Because the overlap changes across the year as zones enter and leave daylight saving on different dates. The grid is computed for the specific date, not from fixed offsets.
What does the .ics download do?
It creates a standard calendar event for the slot you picked, in UTC, so it lands at the correct local time in every attendee’s calendar. Open it with any calendar app or forward it.
How many zones can I compare?
Up to six. The first zone is the reference row whose hours run across the top.
