Best Practices for Global Team Scheduling

Finding a time that works for everyone across multiple zones:

  1. Use the Timeline Grid: Visualize working hours across all team locations simultaneously
  2. Identify overlap zones: Look for times when most team members are within standard business hours (9 AM - 5 PM)
  3. Rotate meeting times: Share the inconvenience fairly so no single timezone always has early morning or late evening calls
  4. Record meetings: Accommodate team members who cannot join live by recording sessions
  5. Share in multiple formats: Always communicate meeting times in multiple zones to avoid confusion

Common timezone pairs for global businesses:

  • New York (EST) to London (GMT): 5-hour difference
  • London (GMT) to Dubai (GST): 4-hour difference
  • Dubai (GST) to Singapore (SGT): 4-hour difference
  • Singapore (SGT) to Tokyo (JST): 1-hour difference
