Find the hours that work for everyone

The meeting planner gives each city a 24-hour row, shades its working hours and its night, and outlines the hours when everyone is at work. It’s part of Open World Clock, one click away on your desktop.

“2 h overlap · 16:00 to 18:00 (Lisbon)”. San Francisco’s day starts at 08:00 here; at 09:00 the overlap would be one hour.

Find a meeting time in four steps

  1. Add the cities. Type each one in the Add city box. Search works by name, country, abbreviation or UTC offset.
  2. Open the planner. Select the planner button in the top bar. Each city gets a 24-hour row.
  3. Set each city’s hours. Click a city’s name to set its working hours and days. Every city starts at 09:00 to 18:00, Monday to Friday.
  4. Pick an hour. Click an hour inside the outlined overlap. Every clock converts to it, and Copy times puts the result on your clipboard.

How to read the grid

  • Columns are the source city’s hours

    The 24 columns are the hours of the chosen day in the converter’s city. Each row shows what time that is locally.

  • Three kinds of hour

    Blue is working time for the whole hour, dark is night (22:00 to 07:00 local), plain is off hours.

  • The overlap

    Hours where every city is working are outlined, and the top line sums them up. A second block adds “+1 more”; none at all says “No overlap”. When no hour works for everyone, the planner outlines the hours when the most cities are at work and names who is outside their hours, for example “Best: 12:00 to 13:00 (New York), 4 of 5 working”.

  • Now, and the rest of the week

    A thin line marks the current time. The date shortcuts (Today, Tomorrow and the next five days) show the days ahead.

  • Keyboard

    Arrow keys move through hours and cities; Home and End jump to the first and last hour.

  • Your time zone, your format

    Hours follow your 12 or 24-hour setting, and cities keep the labels you gave them.

Working hours and days, per city

Teams don’t all work 9 to 6, Monday to Friday. Each city keeps its own start, end and working days, so an office in Riyadh can work Sunday to Thursday and a support desk in Manila can work nights. Reset puts a city back to the default. The hours are saved with your settings, on your PC.

Night shifts

Set an end time earlier than the start, say 22:00 to 06:00, and the editor notes “Ends the next day”. The whole shift belongs to the day it starts: a shift that starts on Friday evening runs until Saturday morning.

Example: a team in Manila working 22:00 to 06:00, Monday to Friday, and an office in New York on 09:00 to 18:00. The planner shows 8 h overlap · 10:00 to 18:00 (New York), because Manila’s night is New York’s working day.

Worked examples

Real results from the planner. Default hours are 09:00 to 18:00, Monday to Friday.

The same two cities on a FridayNo overlap

Wednesday 23 September 2026 unless noted (Thursday 24 and Friday 25 September for Riyadh). Default hours unless noted. The source city is in brackets. With no shared hour, the Best line shows the hours when the most cities work; in the Friday row only London works, so there is no Best line.

The meeting planner for São Paulo, Lisbon, New York, Los Angeles and Singapore on Thursday 24 September, in New York hours. It says No overlap, then Best: 12:00 to 13:00 (New York), 4 of 5 working, and that hour is outlined with a dashed box. Singapore is at midnight then.

No hour works for all five cities, so the planner outlines the one that works for four: “Best: 12:00 to 13:00 (New York), 4 of 5 working”. Singapore is the city outside its hours.

When the clocks change

Clocks change on different dates around the world, and the planner uses each day’s own rules. London and New York share 4 working hours on 21 October 2026, but 5 on 28 October, because Europe has already turned its clocks back and the US waits until 1 November. The same thing happens for two weeks in March. Worth a look before you set up a recurring meeting.
