Meeting Planner
Pick two to six cities and each city's working hours, and see the overlap across the day, hour by hour, with daylight saving taken from the real time zone rules for that date. When nobody overlaps it names the best compromise. Share the plan as a link.
Frequently asked questions
How is daylight saving handled?
Every hour in the grid is a real moment in time, converted to each city with the time zone database built into your browser. So if the US has changed its clocks and Europe has not, as happens for a week in March and a week in October or November, the gap between the cities is correct for the date you pick. Days that have 23 or 25 hours are shown as such.
What counts as a shared hour?
A quarter-hour counts when every city is inside its own working hours for the whole of it. Working hours are start and end times you set for each city, so a late riser in Lisbon and an early team in Sydney can each have their own. An end earlier than the start means an overnight shift.
What if the cities never overlap?
The result says so, and shows the best compromise: the longest stretch when the most cities are at work, and which cities are outside their hours then. That is usually the fairest slot to rotate between teams.
What does the share link contain?
The cities, their working hours and the date, written after the # in the address. Everything after the # stays in the browser and is never sent to our servers or any other, and only cities from the built-in list can be named, so a link cannot carry free text. Leave the date blank to always plan for today.
Why is my city not in the list?
The list holds major cities across the common time zones and daylight saving rules. Pick the nearest city that keeps the same clock: cities in the same zone give the same answer.
