How to convert a meeting time across timezones

  1. Add cities. Type city names (or pick from a dropdown). Add as many as your meeting requires.
  2. Pick a base time. Set the meeting time in any one city — others update live.
  3. Scrub the slider. Drag the time slider to find a slot that lands in business hours for every city.
  4. Copy or share. Copy the meeting time as a formatted string, or get a shareable URL all participants can open.
