Time Zone Overlap Planner

How to use it

1. Enter 2-8 participants with their time zones and working-hour windows, then set meeting duration, start date, date range, and slot interval. Narrow work windows and long meeting durations usually matter more than timezone count alone when overlap disappears.
2. Read the ranked candidate slots with overlap score, fairness score, overall score, local start and end times, plus the 4-week rotation plan. Scores closer to 80-100 usually mean the meeting is workable, while a no-slot result means your work windows are too tight for the chosen duration.
3. Judge recurring meetings by fairness, not just availability. If the same region repeatedly carries 06:00 or 22:00 local slots, the process is operationally unfair even when a legal overlap exists.
4. Use the top two or three candidate windows to set a recurring schedule, then adopt the rotation plan if inconvenience cannot be shared in a single static slot. Before widening the meeting, try adding just 1 hour of flexibility to one region rather than pushing everyone off-hours.
5. Re-run before daylight-saving transitions, major hiring changes, or any shift in regional work hours. Track burden by region over each quarter so one office does not accumulate the inconvenience tax by default.
