How to Add Multiple Time Zones to Google Calendar
If you work with people in other cities or countries, a single time zone view in Google Calendar isn’t enough. Google Calendar lets you display a secondary time zone alongside your primary one — and a world clock sidebar with up to three additional zones. Here’s how to set it all up.
1. Add a Secondary Time Zone to Your Calendar Grid
Google Calendar’s main grid can show two time zones simultaneously — one on each side of the time column.
- Go to calendar.google.com and click the gear icon (⚙️) in the top right.
- Select Settings.
- In the left sidebar, click General → Time zone.
- Under Secondary time zone, check Display secondary time zone.
- Use the dropdown to search for and select the secondary zone (e.g., “Eastern Time”).
- Optionally give each zone a custom label — “NYC” or “London” — to make it easier to read at a glance.
- Click Back to return to your calendar.
Your calendar grid will now show two time columns side by side, making it straightforward to see what 3 PM EST looks like in Pacific Time or vice versa.
2. Enable the World Clock Sidebar
The world clock shows analog clocks for up to three additional locations. It’s useful for a quick reference without cluttering your main grid.
- Click Settings → General → World clock.
- Check Show world clock.
- Click Add time zone and search for locations you want to track.
- Add up to three locations.
The world clock appears on the left side of your calendar. It won’t show event times — it’s purely a live clock reference for knowing what time it is right now in each zone.
3. Switch Between Time Zones Quickly
If you regularly work in a different time zone for a period — say, you’re traveling or running a remote sprint — you can swap your primary and secondary zones without re-entering them.
- Go to Settings → General → Time zone.
- Click the swap icon (↔) between the two time zone dropdowns.
Your primary and secondary zones switch instantly. This is faster than manually reconfiguring everything every time you travel.
4. Set a Time Zone on a Specific Event
When creating an event, you can set a custom time zone for that event — different from your calendar’s default. This is useful for scheduling things like a flight or a call where the time is defined in another zone.
- Click + Create or click on a time slot.
- Click More options to open the full event editor.
- Click the time zone link next to the start time (it shows your current default).
- Search for and select the event’s time zone.
- You can set different time zones for start and end times — useful for events that span zones (like cross-country flights).
Google Calendar will automatically display the event at the correct local time on your calendar grid.
5. Create Events With Guests in Different Time Zones
When you add guests from other time zones, Google Calendar shows their local time when you use the Find a time feature:
- Open the event editor and click More options.
- Click Find a time at the top.
- Add guest emails.
- The scheduling grid shows everyone’s calendars. Hover over a time slot to see the time in each person’s zone.
For recurring cross-timezone scheduling, tools like Carly can handle this automatically — finding times that work across multiple calendars without the manual back-and-forth.
6. Set Your Home Time Zone for Traveling
If you travel frequently, Google Calendar has a “home” time zone concept that keeps your regular schedule anchored even when your device adjusts to a local zone.
- Go to Settings → General → Time zone.
- Check Ask to update my primary time zone to [location] when I travel.
- Set your Home time zone to your usual location.
When you’re traveling, Google will prompt you to update your primary zone. Events created while abroad will reference the local zone, but your home events stay correctly anchored.
7. Troubleshooting Common Time Zone Issues
| Issue | Cause | Fix |
|---|---|---|
| Events appear at the wrong time | Event was created in a different time zone | Open the event and check the time zone label next to the time |
| Secondary time zone not showing | Option not enabled | Settings → General → Time zone → enable secondary zone |
| World clock not visible | Feature off or browser zoom too narrow | Enable in Settings → World clock; widen your browser window |
| Guest sees a different time | They’re in another zone | Google Calendar adjusts automatically — no action needed |
| Time zone switched after travel | Device auto-updated | Settings → Time zone → restore your home zone |
Best Practices for Multi-Timezone Scheduling
- Label your zones. “NYC” and “SF” are faster to read than “Eastern Time (US & Canada).”
- Anchor recurring meetings to a specific zone. If your weekly team call is always 10 AM EST, create it in EST so it doesn’t shift when attendees travel.
- Use “Find a time” before proposing times. Don’t guess what works — let the grid show you.
- For large groups, collect availability first. Carly’s group scheduling lets everyone mark their free times (calendar-connected), so overlaps surface automatically across zones.
