How to Use the Global Golden Hours Tool

1

Add Your Cities

Start typing in the search box to find and add cities. The tool will show autocomplete suggestions from thousands of cities worldwide. You can add up to 5 cities to compare. Your current timezone is automatically detected.

  • Green: All cities in working hours (9 AM - 5 PM)
  • Orange: Partial overlap (some cities in working hours)
  • Gray: Off-hours or night time
4

Find the Best Overlap

The tool automatically identifies and highlights the "Best Overlap Window" - the longest continuous period when all selected cities are in working hours. This is your ideal time slot for scheduling meetings or collaborative sessions.

💡 Pro Tips

  • • Consider rotation: For teams with poor overlap, consider rotating meeting times to distribute inconvenience fairly
  • • Document decisions: Export and share the visual to help everyone understand the timezone constraints
