Timezone Meeting Planner
Select your participants' cities, and this planner shows the overlapping working hours across every timezone.

About Timezone Meeting Planner
UTC, Coordinated Universal Time, is the fixed reference point every other timezone is expressed as an offset from, but the practical complication is that daylight saving transitions happen on different dates in North America, Europe, and not at all in most of the Southern Hemisphere, which means the gap between two cities' local time can actually shift by an hour depending on the week. This planner accounts for that shifting offset rather than treating timezone gaps as fixed.
Scheduling a call across three or four countries by mental math alone is where meeting-time mistakes come from most often, especially around the weeks when the US and Europe aren't yet or no longer aligned on daylight saving, a mismatch window that trips up even experienced remote teams every single year.
Finding a window where every participant is in reasonable working hours, not just technically awake, matters for meeting quality too. A call where one participant is attending at 11pm tends to be shorter, less engaged, and less useful than one scheduled inside everyone's actual workday.
Select each participant's city or country from the timezone database. The planner displays a side-by-side timeline of local hours and highlights the windows where everyone overlaps during standard working hours.
Meeting schedules often reveal business relationships worth keeping confidential. The planner runs entirely in your browser, with no location or schedule data transmitted to a server.
FAQ
Frequently asked questions
How do daylight saving changes mess with international scheduling?
The US, Europe, and most of the Southern Hemisphere shift clocks on different dates (or not at all), which means the time gap between two cities can change by an hour for a few weeks each year without anyone adjusting anything manually.
What exactly is UTC, and why does it matter here?
UTC is Coordinated Universal Time, the fixed baseline every timezone is measured against as a positive or negative offset, making it the stable reference point for any cross-timezone calculation.
Can this help plan asynchronous work, not just live meetings?
Yes, seeing when different regional teams are actually active helps set realistic response-time expectations for async collaboration, not just live call scheduling.
What's the best way to avoid scheduling a meeting during someone's overnight hours?
Check each participant's local time directly in the planner rather than assuming based on the time difference alone, since a 9-hour difference can place a meeting anywhere from early morning to late night depending on the specific time zones involved, not just the hour gap.
Do daylight saving changes happen on the same date everywhere?
No, which is a common scheduling trap. The US and Europe switch clocks on different dates each year, and many countries don't observe daylight saving at all, so a meeting time that worked last month can silently shift by an hour without anyone changing their calendar entry.
Is there a time zone that's considered neutral for global teams?
UTC is the standard reference used for coordination since it doesn't observe daylight saving and isn't tied to any one region, which is why this planner anchors around it, letting every participant's local time get calculated consistently from the same fixed point.
