Meeting Planner
Pick two to four cities and a date; get all 24 hours side by side with working hours shaded and the slots that work for everyone highlighted. The fastest honest answer to "when can we all meet?"
Compare working hours
Your first city anchors the grid; add up to three more.
Choose at least two places to compare.
Finding the fair slot
Two-city overlaps are usually easy; the pain starts at three. A New York–London pair shares a comfortable three-hour window (9 AM–noon Eastern is 2–5 PM in the UK); add Singapore and the highlighted rows vanish, because Singapore's working day ends before New York's begins. That is not a scheduling failure — it is geography — and the honest response is the grid's shading: pick the row that puts the fewest people outside working hours, and rotate the inconvenience across meetings.
Frequently asked questions
How do I read the grid?
Each row is one hour of the day in your first city, translated into the local time of every other city on that date. Shaded cells fall inside typical working hours (9:00–17:00); a highlighted row means the hour is inside working hours everywhere — your candidate meeting slots.
Why does the grid need a date?
Because overlaps move with daylight saving. The London–New York overlap shifts by an hour for a few weeks each spring (and about a week each fall), and Sydney flips the other way entirely. The grid computes each city’s clock for the specific date, so what you see is true for that day, not an annual average.
What do the +1d / −1d marks mean?
The hour lands on the next or previous calendar date in that city. A 6 PM Tuesday call in San Francisco is already Wednesday morning in Sydney (11 AM in the northern summer; the exact hour shifts with each city’s daylight saving) — the mark is the difference between "Tuesday" in the invitation and the Wednesday your Australian colleagues actually experience.
What if there is no highlighted row?
Some spreads (San Francisco–London–Singapore, for instance) genuinely have no 9-to-5 overlap. Then the shading shows the least-bad options: rows where most cities are in working hours and the rest are in early morning or evening rather than the middle of the night. Rotating who takes the awkward slot is common courtesy.
The grid is computed locally in your browser from its IANA time zone data; nothing you enter is transmitted. Working hours are shaded at the common 9:00–17:00 convention. See the methodology page.
