Scheduling a meeting across three timezones by mentally converting hours back and forth is a recipe for a 4am invite. This tool does the math for you and shows exactly which hours work for everyone.
What Is the Meeting Time Planner?
Meeting Time Planner is one of the tools in WebdevToolbox’s Productivity category. Add each teammate’s timezone and working-hours window, and see a 24-hour chart (in your own local time) showing where those windows overlap.
How to Use It
- Open the tool at /tools/meeting-planner.
- For each participant, set their timezone and their local working hours (e.g. 9 to 17).
- Read the chart — green bars mean everyone is available at that hour; red means no one is.
- Check the summary line for the exact list of fully-overlapping hours.
Key Features
- Real timezone math — uses the browser’s Intl API against each IANA timezone name, so current DST offsets are reflected automatically.
- Overnight-window support — working hours that wrap past midnight (e.g. 22–06) are handled correctly.
- Add as many participants as you need — not limited to two people.
- 100% local — no calendar integration or data leaves your browser.
When to Use the Meeting Time Planner
- Distributed team standups — find a time slot that doesn’t force anyone into an odd hour.
- Client calls across regions — quickly check overlap before proposing times.
- Recurring meeting setup — decide on a standing time that stays fair across timezones.
