Meeting Planner - Find Overlapping Work Hours Across Time Zones

Planning Meetings Across Time Zones

The planner draws one 24-hour strip per city, aligned on the same moment in time: every column is the same instant everywhere in the world, and the number in each cell is the local hour in that city. Green cells fall inside standard working hours, 9:00 to 17:00, and a column turns indigo when it is green for every city at once. That indigo band is your candidate meeting window.

Some combinations simply have no overlap. Amsterdam and Singapore share a comfortable morning-to-afternoon window because the gap is only 6 or 7 hours, but Amsterdam, New York, and Singapore together usually produce zero indigo columns: when it is 15:00 in Amsterdam it is 9:00 in New York but already 21:00 in Singapore. In that case click any column to see the exact local times and pick the least painful compromise, or rotate the inconvenient slot between regions from one meeting to the next.

The tool uses your browser's built-in IANA time zone database via the Intl API, so daylight saving time is applied correctly for the current date: the strip for today in late March can differ from the strip in early November because the US and Europe switch DST on different weekends, which temporarily shifts the overlap by an hour. Offsets shown next to each city name are live for today, not fixed labels.

A practical rule of thumb for recurring calls: teams spread over 8 or fewer hours of offset can usually find a fair daily window, while spreads above 10 hours work better with asynchronous updates plus one or two anchor meetings per week. To convert a single specific timestamp rather than scan a whole day, the Timezone Converter does direct one-off conversions, and the Meeting Cost Calculator shows what that recurring call actually costs in salary terms.
