How to use the world clock
- Your own time is always at the top. Add a city for each place you care about; use the arrows to put them in order.
- To plan a call, drag the slider forward or back. Every clock moves together, and cities where it’s working hours turn green.
- “Tomorrow” or “yesterday” shows when a city is on a different date from you.
Questions
Does it know about daylight saving time? Yes. It uses your browser’s time zone data, which includes the daylight saving rules for each place.
What does UTC+5:30 mean? That place is five and a half hours ahead of Coordinated Universal Time, the world’s reference clock (about the same as London in winter).
