Working Hours Overlap Finder

Add multiple cities / timezones with their working hours (default 9am-6pm), and the tool generates a heatmap showing which UTC slots have the most overlap. Visual representation of when a meeting can include the most people without anyone being outside working hours.

When to use this

Use for: scheduling global team meetings without anyone joining at 3am, finding optimal one-time call slots with international clients, planning recurring meeting cadences that distribute timezone pain across the team.

Frequently Asked Questions

What if there's no overlap at all?

Some global team distributions (Tokyo + San Francisco) have minimal natural overlap. Options: rotate the meeting time (each region takes turns on the inconvenient slot), record + async-share instead of meeting, or split the team into regional sub-meetings.
