Meeting planner

Add the zones your team works in and the band below shows every hour of the day at once, with working hours shaded — so the overlap is a shape you see rather than a sum you do.

Zones in this plan

  • Los Angeles
  • New York
  • London
  • Mumbai
  • Tokyo

There is no hour when everyone is inside working hours. Widen the working day, or accept that someone joins early or late.

Each column is the same instant. Shaded cells are working hours; the row header shows the offset.

How to read the band

Every column is one instant. Read down a column and you see what the clock says in each place at that same moment — which is the thing a list of offsets makes you compute in your head, and the thing people get wrong.

Three shades: working hours carry a coloured top border, the hour either side is lighter, and the rest is flat. The border matters as much as the fill — the distinction never rests on colour alone, so it still reads if you cannot separate those two blues.

When there is no overlap

Some teams genuinely have none. A 09:00–18:00 day in Los Angeles and the same in Mumbai share nothing at all — Mumbai’s working day ends before Los Angeles wakes up. New York and Sydney are stranger still: they share exactly one hour from November to March, when the gap is 16 hours, and nothing whatsoever from April to October, when it narrows to 14. Same two cities, opposite answer, and the only thing that changed is the date.

When that happens the planner says so rather than shading something in and hoping. The realistic choices are to widen the working day for one side, to alternate which side takes the awkward call, or to stop meeting synchronously. Pretending a 22:00 slot is fine is how people quietly burn out.

Common questions

How many time zones can I add?
Between two and ten. Past ten the band stops being readable at a glance, which is the entire reason to use a band rather than a list of numbers — so the limit is a design decision rather than a technical one.
What counts as working hours?
Whatever you set. The default is 09:00 to 18:00 local time in every zone, and both ends are adjustable. The hour either side of the working day is shaded more lightly: it is reachable, but you are asking someone a favour.
Why do some rows show times ending in :30 or :45?
Because those zones are genuinely offset by half or three-quarters of an hour. India is UTC+05:30, Nepal is UTC+05:45, the Chatham Islands are UTC+12:45. Each column in the band is the same instant, so those rows show the real local reading rather than a rounded one.
What if there is no overlap at all?
The planner says so plainly instead of suggesting a compromise nobody agreed to. Los Angeles and Mumbai share no minute of a 09:00–18:00 day, and no amount of grid shading changes that — someone has to move. Widening the working day or splitting into two calls are the honest options.
Does the plan survive a page reload?
Yes. Your zones, date and working hours are written into the URL, so you can bookmark a plan or send it to someone and they see exactly what you see. The zone list is also kept in your browser so the planner remembers your team next time.
Does it account for daylight saving?
Yes, on the date you choose. Pick a date in March or October and you will see rows shift relative to each other, because that is what actually happens — the zones change their clocks on different days.
