How to Show Multiple Time Zones in Google Calendar and Outlook

Add extra time-zone scales in Google Calendar or Outlook to read a meeting's local time in several places. Both have native desktop options. The scales provide additional references beside the same appointment; they do not create extra events or change its time.

Google Calendar on a computer

On a computer, open Google Calendar, select Settings, then find Time zone under the general settings.

Check the primary zone first. Enable the additional-zone display and choose the secondary zone. Google's current instructions also describe a tertiary zone, so you can display three references. Use city-based zones and recognizable labels where available.

Google's official time zone guide also describes its world clock, which can show current times for additional places. A world clock and the time scale beside a calendar grid are useful for different tasks: one answers “what time is it there now?”, while the other helps place an event on a particular day.

Switch to day or week view and read a future meeting against each zone's scale. Compare those times with its invitation, including a week near a clock change. Phone apps may use a different layout from the desktop.

Add zones in Outlook on the web or new Outlook

Open Settings → Calendar → View and find Time zones. Check the main display zone, then use Add time zone for another reference.

Choose the city, label it clearly, and enable its calendar display where prompted. Put the zones you compare most often next to one another.

Microsoft's version-specific guide describes the web, new Outlook, and classic Outlook routes. Use the section matching your app rather than searching for a desktop ribbon in the browser.

Add zones in classic Outlook

Open File → Options → Calendar and find the time zone section. Enable a second zone and, if your version supports it, a third.

Microsoft notes that recent Microsoft 365 versions can show three zones, while some older classic versions support two. The display also depends on the calendar view. If the extra scale is absent, check a day or week view before deciding the setting failed.

Use labels such as “Home,” “London,” or “New York.” A city name avoids abbreviations shared by several regions.

Keep event zones separate from display zones

A calendar display zone tells you how to read the grid. The event's zone helps define when the appointment occurs, particularly for recurring local-time schedules.

For example, a meeting anchored at 9 AM New York time may appear at a different London hour during the weeks when the countries change clocks on different dates. Adding both scales helps reveal that; it does not remove the seasonal difference.

Review recurring meetings across daylight-saving transitions. If a time seems wrong by one hour, inspect the event and display zones before moving it.

For travel, decide whether you want the grid to follow your device's current zone or stay anchored to home. Choose the calendar display behavior you want while traveling.

When a cross-provider view helps

If all your appointments are in Google or all are in Outlook, the native display may be enough. Adding a sync tool solely to see a second zone is often unnecessary.

If you have commitments spread across Google, Microsoft, iCloud, or CalDAV accounts, a combined workspace can be more convenient. Avum's calendar view provides a cross-provider display with time-zone tools. It works alongside your existing calendar apps and account-to-account copying.

A view helps you inspect your schedule, while Sync Rules maintain chosen destination copies. Seeing several calendars together doesn't change which calendars a colleague's booking tool checks.
