Tips for multi-timezone collaboration

  • Asynchronous Updates: Rely on recorded walkthroughs and documented PRs for handoffs when offset exceeds 6 hours.
  • Shared Calendars: Configure secondary timezone displays in Google Calendar or Outlook to prevent accidental off-hours invitations.
  • Rotated Call Times: For regular cross-regional standups, alternate weekly meeting times so no single hub constantly sacrifices personal evenings.
