Meeting Time Finder
Find overlapping working hours across up to 3 time zones, so you can schedule a meeting everyone can actually attend.
Converting one specific time between zones (what the Time Zone Converter does) answers a different question than finding when several people in different zones are all simultaneously available — the second question is what actually matters when scheduling a meeting. This tool takes up to three time zones and a working-hours window for each, then scans every hour of a chosen date to find the windows where everyone is inside their own working hours at the same moment. If no overlap exists, it tells you that directly instead of suggesting an inconvenient time.
No overlapping working hours found for these time zones and window. Try widening the working-hours range.
How to Use This Calculator
1. Select each participant's time zone
Choose up to three time zones, one per participant or group.
2. Set the working-hours window
The local start and end hour each person is generally available, e.g. 9 to 17.
3. Pick a date
Time zone offsets can shift with daylight saving time, so results are calculated for the specific date you choose.
4. Read the overlapping hours
Every UTC hour where all selected zones are within working hours, shown in each person's own local time.
Frequently Asked Questions
How is this different from the Time Zone Converter?
The Time Zone Converter answers "what time is it in Tokyo when it's 3pm in New York?" — a single conversion. This tool answers "when can someone in New York and someone in Tokyo both be in a meeting?" — a search across the whole day for overlapping availability, which is a genuinely different calculation.
Why does the result change if I pick a different date?
Time zones that observe daylight saving time shift their UTC offset on specific dates each year. The overlap window is calculated using each zone's actual rules for the exact date selected, so it can differ between, for example, a January date and a July date.
What if there's no overlap at all?
It happens, especially with zones roughly 12 hours apart. When there's no true overlap, the practical options are an early morning or late evening call for one or more participants — this tool tells you plainly when that's the case rather than suggesting a time outside anyone's working hours.
Common Mistakes
❌ Assuming a good meeting time in January still works in July
If any participant's zone observes daylight saving time, the overlap window can shift by an hour across the year. Recheck for dates far from when you first found a good time, especially around DST transition dates.
❌ Picking working hours that are too narrow
A tight 9-to-5 window in every zone leaves little room for overlap once three or more time zones are involved. Widening the window even by an hour on one side can reveal an overlap that a strict 9-to-5 window misses entirely.
❌ Forgetting that zero overlap is a real, common outcome
Some time zone combinations (e.g. US West Coast and East Asia) simply don't share standard working hours. When that happens, the realistic options are an early or late call for one side, not a hidden overlap this tool failed to find.
