World clock and time-zone comparison
The world clock helps you compare current local times without calculating offsets by hand. Add the cities relevant to your team, family or trip and use the shared view to identify reasonable calling hours.
How to use it well
- Select Add city and search for the location you need.
- Compare the displayed dates as well as times; locations can already be on different calendar days.
- For a scheduled event, confirm the organizer’s named time zone and date before sending invitations.
Good uses for this tool
- Find overlapping working hours for distributed teams.
- Avoid calling friends or family during the night.
- Check destination time before travel or a live online event.
