Timezone Overlap Planner – Compare Time Zones Online Easily

How to Find a Meeting Time Across Time Zones

1. Start with the default cities, London, New York, Los Angeles and Mumbai, or remove the ones you don't need with the X next to each name.
2. Add cities from the list, up to 8 of the 14 available.
3. Look for teal blocks in the grid: they mark hours when every selected city is inside working hours.
4. Read the summary under the grid. It shows the overlap window in UTC, or says there is no full overlap.

How the Grid Works

• Each column is one hour of today's date in UTC, and each row shows a city's local time for that hour. Hover over a block to see the exact local time and date.
• Green blocks are working hours, 9:00 to 17:00 local time. Dark blocks are night hours, before 6:00 and from 22:00. The current hour is outlined.
• Each row shows the city's current time and UTC offset, such as UTC+5:30 for Mumbai, and updates every minute.
• Daylight saving time comes from your browser's time zone data, so offsets are correct for today, including on the day the clocks change.

Limitations to Know

• The grid shows today only. There is no date picker, so to plan a meeting in a week when the clocks change, check the overlap again after the change.
• Working hours are fixed at 9:00 to 17:00 and can't be edited.
• Overlap is checked per hour, using each city's local time at the start of the hour. For cities with half-hour offsets, such as Mumbai, an hour that is only partly inside working hours counts by its start time.
• Your selection isn't saved, so the default cities return when you reload.

When There Is No Overlap

Cities far apart, such as Los Angeles and Mumbai, often share no working hours at all. In that case, rotate meeting times so the same people aren't always joining early or late, split the meeting into two regional sessions, or move the discussion to written updates.
