Time Zone Meeting Planner
Find a meeting time that works everywhere.
Scheduling a call across countries usually means squinting at a world clock and doing math in your head. The Time Zone Meeting Planner does that math for you. Pick your time zone, pick the other person's time zone, and set the working hours you both want to respect. The planner then finds every hour today when both of you are inside your working window and shows each overlapping slot as the local time in both places at once.
Because it runs on your browser's built-in date and time engine, it automatically applies the correct daylight saving offset for the date you are viewing. That means fewer missed meetings and no more "wait, are we an hour off now?" moments. It is a fast way to spot a fair, sensible time before you send the invite.

How to use the time zone meeting planner
- Choose your own time zone from the first dropdown, which lists standard IANA zones such as America/New_York or Europe/London.
- Choose the other person's time zone from the second dropdown.
- Set your working hours by entering a start and end time, for example 9 to 17 for a standard 9-to-5 day.
- Confirm the working hours for the other person, adjusting them if their schedule differs from yours.
- Read the results, where each overlapping hour is listed with the local time shown side by side for both zones.
- Pick a slot that works for both of you and use it to send your meeting invite.
Worked example
Suppose you are in New York and your colleague is in London, and you both work 9 to 17. New York is five hours behind London, so when it is 9:00 in New York it is already 14:00 in London. The planner compares the two windows and finds the shared hours run from 9:00 to 12:00 New York time, which is 14:00 to 17:00 London time. After noon in New York, London has clocked off, so those hours drop out. You would schedule the call somewhere in that three-hour band, perhaps 10:00 New York time (15:00 in London), giving both of you a comfortable mid-morning or mid-afternoon slot.
Common mistakes to avoid
- Forgetting daylight saving time when doing the math by hand, since the gap between two zones can shift by an hour in spring and fall.
- Overlooking half-hour and 45-minute zones such as India (UTC+5:30) or Nepal (UTC+5:45), which do not line up neatly with whole-hour offsets.
- Assuming the offset you calculated last month still applies, when one region may have changed clocks and the other may not.
- Using a city name instead of the correct IANA zone, so that a place with its own rules gets grouped with a neighbor that switches clocks differently.
- Treating the shared window as the whole workday, when lunch breaks or early finishes can shrink the realistic meeting time.
Frequently asked questions
Does it handle daylight saving time?
Yes — conversions use each location's current DST rules.
What if there is no overlap between our working hours?
When two zones are far enough apart, no hour falls inside both working windows and the planner shows an empty result. In that case someone has to flex outside normal hours. Try widening one person's working range, or agree to alternate who takes the early or late call so the burden is shared fairly.
Can I set different working hours for each person?
Yes. You can give each side its own start and end time, which is useful when one person keeps an earlier or later schedule. The planner only counts an hour as shared when it sits inside both windows, so the result reflects both people's real availability.
Do I need to install anything or create an account?
No. The planner runs entirely in your browser using its built-in time functions, so nothing is downloaded and no sign-up is required. If you also need to convert other measurements while you plan, our <a href="/tools/unit-converter/">unit converter</a> works the same way, right in the page.
