Time Zone Planner

Find a meeting time that works across time zones, then share the plan.

This app does not connect to your calendar, send invites or poll attendees. It uses your browser’s IANA time zone rules. Your entries stay in this browser unless you share a link or file.

24-hour overlap grid

The grid suggests whole UTC hours. Your chosen time can include minutes. Labels are estimates from the working hours you enter, not attendance or availability.

Add a participant to see the overlap grid.

Share plan

The link includes the meeting title, participant names, zones and working hours. Anyone with the link can read them. Share only with people you choose.

Your data

Download a backup before clearing browser data. Opening a shared link or backup shows a preview; it changes this plan only after you confirm.

Storage and recovery

If storage is damaged, download the saved bytes before deleting it. Load the latest plan after another tab changes it; unsaved form changes will be discarded.
