How meeting time planning works
Meeting time planning identifies the overlapping portion of each participant's working hours after converting all times to a common reference (typically UTC). Each timezone's working hours (e.g., 9 AM–5 PM local) are mapped onto a 24-hour UTC timeline. The intersection of all participants' working-hour ranges is the window where everyone is available.
Worked example
How to use the meeting time planner
Add participant timezones
Select each participant's timezone from the dropdown. Add up to 5 locations.
Set working hours
Adjust the default 9-5 working hours if your participants have different schedules.
Find the green zone
Look for the green highlighted area in the 24-hour grid — that is your perfect meeting window.
Meeting time planning tips
Start with the most constrained timezone
When scheduling globally, begin with the participant who has the least flexibility (e.g., the person whose work hours are most restricted). Build the schedule around them.
Rotate meeting times fairly
If no perfect overlap exists, rotate the inconvenient time among participants. One week the US team joins early, next week the Asia team stays late.
Consider lunch hours
Standard 9-5 hours include lunch breaks around noon to 1 PM local time. When an overlap seems tight, check if it lands during lunch in any participant's timezone.
Why meeting planning is hard
Scheduling across timezones is challenging because the Earth's 24-hour day means that when it is morning in one location, it is evening in another. The typical 9-to-5 business day in the Americas, Europe, and Asia have only a few hours of overlap at best. This tool eliminates the mental math by visualizing everyone's working hours on a single timeline.
Best overlapping hours for common region pairs
US East (New York) and Western Europe (London/Paris): 13:00-17:00 UTC gives 9 AM-1 PM ET and 2-6 PM CET — 4 hours of overlap. US West and East Asia: 16:00-18:00 UTC gives 9-11 AM PT and midnight-2 AM in China — only 2 hours, often requiring one party to adjust their schedule. Europe and East Asia: 7:00-9:00 UTC gives 8-10 AM CET and 3-5 PM in China — a solid 2-3 hour window.
Limitations and considerations
While meeting time planners are powerful scheduling tools, they have several limitations worth understanding. First, the tool assumes standard 9-to-5 business hours for all participants, but many professionals work non-traditional schedules. Nurses, retail workers, and hospitality staff often work shifts that fall outside typical business hours. The planner cannot account for rotating shifts, split schedules, or part-time availability. Second, the tool does not factor in lunch breaks. A participant who appears available from 9 AM to 5 PM may actually be unavailable between noon and 1 PM for lunch, which can reduce the actual overlap window by one hour or more. Third, cultural differences in work schedules are not considered. In some countries, the workday includes a midday break spanning two hours. In Spain and Italy, many businesses close for lunch between 1 PM and 3 PM, then resume until 6 PM or 7 PM. The standard 9-to-5 model does not reflect this pattern. Fourth, the tool cannot handle holidays and personal days off. If a participant has a public holiday or vacation day, the calculated overlap becomes invalid. Fifth, the planner does not account for partial availability within a day. Someone may be free only during certain hours due to standing meetings or personal commitments. Despite these limitations, the tool provides an excellent starting point for finding suitable meeting windows. Users should treat the output as a suggestion and confirm actual availability with participants.
Tips for best results
Set the correct date
Always set the correct date before adding timezones. Daylight saving time transitions can shift timezone offsets by one hour. The tool handles DST based on the selected date, so an incorrect date produces incorrect offsets.
Verify participant timezones
Confirm each participant's correct timezone. Large countries span multiple timezones. Assuming someone is in Eastern time when they are in Central time shifts the overlap window by one hour.
Check the overlap bar
Use the overlap bar as a quick reference for usable time. If the bar shows less than two hours, consider whether the meeting can fit in that window or if an asynchronous approach works better.
Account for recurring meetings
For recurring meetings, check the overlap for each occurrence date. DST changes can shift the window by one hour between March and April or October and November in many regions.
Rotate inconvenient times fairly
When the overlap is small, rotate the meeting time among participants so no single person always bears the inconvenience of attending outside regular hours.
Frequently asked questions
How does the meeting time planner work?
You add timezones for each participant, set standard working hours (default 9 AM - 5 PM), and the tool shows a 24-hour grid with colored bars showing availability. Green bars highlight the overlap where everyone is available.
What timezone data is used?
The tool uses the IANA timezone database via JavaScript Intl.DateTimeFormat. All major timezones are supported, and the list includes preset major cities for convenience.
What are the best overlapping hours for US-Europe meetings?
The best overlap is typically 13:00-17:00 UTC (9 AM - 1 PM Eastern US, 2-6 PM Western Europe). This covers late morning in the US and late afternoon in Europe.
What are the best overlapping hours for US-Asia meetings?
Morning US time overlaps with evening Asia time. For example, 8-10 AM Eastern US (12-2 PM UTC) corresponds to 8-10 PM in China and Japan. This is often the most practical window.
What are the best overlapping hours for Europe-Asia meetings?
The morning in Europe overlaps with the afternoon in Asia. 8-10 AM UTC (9-11 AM Western Europe) corresponds to 2-4 PM in India, 4-6 PM in China, and 5-7 PM in Japan.
How many timezones can I add?
You can add up to 5 timezones. This covers most common scenarios while keeping the display clear and readable.
Can I change the working hours?
Yes. Use the working hours start and end time inputs to customize the range. The default is 9:00 to 17:00 (standard business hours), but you can adjust it to any schedule.
What does the 24-hour grid show?
The grid displays all 24 hours of the day. Each timezone has a colored bar showing its working hours. The overlap area is highlighted in green to show the window where all participants are available.
Does this handle daylight saving time?
Yes. The tool uses your browser Intl.DateTimeFormat which automatically accounts for DST. The timezone display updates based on the current date.
Is this better than a world clock?
Yes for meetings. While a world clock shows current times everywhere, this planner specifically identifies overlapping business hours, making it much easier to find meeting times that work for everyone.
