Meeting Time Zone Planner – Schedule Across Any Time Zone
Coordinating a call, interview, or standup across a distributed team means juggling UTC offsets, daylight saving time, and everyone’s idea of a reasonable hour to be awake. The Meeting Time Zone Plannerremoves the manual math: pick a base location and a proposed meeting date and time, add the cities of everyone attending, and the tool instantly shows what that moment looks like everywhere else — plus whether it falls inside or outside each participant’s working hours.
How the conversion works
The planner treats your base date and time as a single absolute instant, then reformats that same instant into every participant time zone using the browser’s built-in Intl.DateTimeFormat API, which ships with the IANA time zone database. That means daylight saving transitions, half-hour offsets like UTC+5:30 for India, and 45-minute offsets like UTC+5:45for Nepal are all handled automatically and correctly for the specific date you choose, not just “right now.”
Reading the working-hours badges
Each participant row is classified against a configurable working-hours window (9 AM–6 PM by default, but you can set any start and end hour, including an overnight window for night-shift teams). A Working hours badge means the meeting falls comfortably inside that window. An Early/latebadge flags a time within an hour of the boundary — early morning or late evening but not unreasonable. An Outside hoursbadge means the meeting would land in the middle of that participant’s night or well outside their typical day.
Spotting the date-line problem
When participants are spread across enough time zones, the same meeting instant can fall on a different calendar date for some of them. The Day column tags any location that is a day ahead or behind the base location’s date, so you never accidentally send an invite for “Tuesday” that actually lands on Wednesday morning for a participant near the International Date Line.
Finding the best overlap window
Rather than guessing, use the Best Overlap Windowssection to let the tool do the searching. It scans every hour of the meeting date in your base time zone and, for each hour, counts how many locations (your own included) would be inside working hours at that moment. Hours that tie for the highest count are grouped into ranked windows, so you can see at a glance whether a full team overlap exists or whether you’re choosing between partial-overlap compromises.
Generating a shareable invite
Once the times look right, the Invite Textbox produces a plain-text summary listing the meeting time in every participant’s local time zone, ready to paste directly into an email or calendar invite. This keeps everyone informed without asking them to do their own conversion, and it clearly marks any participant for whom the meeting falls on a different calendar date.
Who this tool is for
The Meeting Time Zone Planner is built for remote and hybrid teams, recruiters scheduling interviews across countries, freelancers working with international clients, and anyone who needs to convert a single proposed time into a dozen local equivalents without opening a spreadsheet. Because the underlying conversion is DST-aware for any date — not only the current one — it also works well for planning meetings weeks or months in advance.
