How to Change the Time Zone in Google Calendar (2026)
Google Calendar’s primary time zone controls how every event time is displayed. If it’s wrong, all your meetings appear shifted by a few hours, and events you create can land at the wrong time for other people. You can also display a secondary time zone alongside it and override the zone for individual events.
This guide covers the desktop web version (where all the settings live) and the differences in the Android and iPhone apps. Secondary time zones and per-event zone settings are fullest on desktop.
1. Change Your Primary Time Zone on Desktop
This is the setting that affects how your whole calendar displays.
- Open Google Calendar in a browser
- Click the Settings gear icon (top right) → Settings
- In the left menu, under General, click Time zone
- Open the Primary time zone dropdown
- Select your correct time zone
The change saves automatically — there’s no Save button. Your calendar redraws with every event displayed in the new zone. The events themselves keep their absolute time; only the display shifts.
2. Add a Secondary Time Zone
A secondary time zone shows a second column of times in your day and week views — handy when you work across regions.
- Go to Settings → General → Time zone
- Check Display secondary time zone
- Choose the secondary zone from its dropdown
- Add a short label for each zone (e.g., “NYC” and “London”) so the columns are easy to read
Both zones now appear as labeled time columns down the left side of your Day and Week views. To swap which is primary, click the Swap arrows between the two zone dropdowns.
3. Set a Time Zone for a Single Event
Sometimes one event needs a different zone — for example, a flight or a meeting hosted in another region.
- Create a new event or open an existing one and click Edit
- Click the event’s time
- Click Time zone
- Choose a zone for the event
- (Optional) Toggle Use separate start and end time zones to set different zones for the start and end — useful for travel itineraries
- Click Done, then Save
The event stays pinned to that zone no matter what your primary calendar zone is, so it always shows at the correct local time.
4. Change the Time Zone in the Mobile App
The Google Calendar app usually follows your phone’s system time zone, but you can override it.
Android:
- Open the Google Calendar app
- Tap the menu (☰) → Settings
- Tap General
- Turn off Use device time zone
- Tap Time zone and choose the zone you want
iPhone / iPad:
- Open the Google Calendar app
- Tap the menu (☰) → Settings
- Tap General
- Turn off Use device time zone (Google Calendar follows the iOS system clock by default)
- Tap Time zone and pick your zone
Note: Secondary time zones and per-event separate start/end zones aren’t available in the mobile apps — set those on desktop. The app will display them correctly once you’ve configured them on the web.

Troubleshooting
All my events are showing a few hours off.
Your primary time zone is wrong. Reset it under Settings → General → Time zone on desktop, or turn Use device time zone back on in the mobile app so it follows your phone.
My events shifted after I changed time zones — are they broken?
No. Google Calendar preserves each event’s absolute time and re-displays it in your new zone. A 3:00 PM Eastern meeting correctly shows as noon Pacific. Don’t drag events to “fix” them.
The secondary time zone option is missing.
Secondary time zones are a desktop-web-only feature. Open Google Calendar in a browser and look under Settings → General → Time zone — it isn’t in the mobile apps.
A guest in another country saw the wrong time.
Each guest sees the event in their own calendar’s time zone automatically, so this usually means the event was created with the wrong event-level zone. Open the event, check its Time zone, correct it, and save to send an update.
The mobile app keeps reverting my time zone.
With Use device time zone on, the app follows your phone’s system clock. Turn it off and set the zone manually, or change your phone’s system time zone instead.

"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
