In Google Calendar, you can quickly confirm your gut feeling with a world clock — and find out the precise time just about anywhere, more or less regular daylight saving times already applied.
See Who Is Awake or Asleep with the Google Calendar World Clock
To have Google Calendar show you the current time in cities and time zones around the world:
- Make sure World clock is enabled (see below).
- To make sure the right Google Calendar pane is visible, click the leftward arrow at the rightmost edge of Google Calendar if you see it (instead of the pane).
- To make sure you see the world clock, click the World clock header if the box is collapsed.
For Google Calendar, the night lasts from 6 p.m. (18:00) to 7 a.m. (07:00). During these hours, the clock background turns black and a stylized moon appears.
To add or remove cities and time zones from the Google Calendar world clock:
- Click Settings in the World clock box.
- Make sure all (and only) desired cities and time zones are checked.
- Click Save.
