Change your time zone in three steps
Open Google Calendar in a web browser, click the gear icon in the top right corner, and select Settings. Scroll down to the Time zone section, click the dropdown menu, and search for or select your time zone. Google Calendar saves the change automatically — you do not need to click a separate save button.
The time zone you set here applies to all events in your calendar, including ones you created before the change. If you share your calendar with others, they see events in their own time zone, not yours, so changing your setting does not affect what they see.
On a phone or tablet, you cannot change the time zone within the Google Calendar app itself. Instead, change your device's time zone in your phone's system settings, and Google Calendar will use that setting. The steps vary by phone type: on Android, go to Settings > System > Date and time > Time zone; on iPhone, go to Settings > General > Date and Time > Time Zone.
Key Takeaways
- You change your time zone through Google Calendar Settings on a computer, not through the app on your phone.
- The change applies to all your events at once, and Google Calendar saves it automatically without a separate confirmation step.
- On a phone, change your device's system time zone instead, and Google Calendar will read that setting.
- Other people who share your calendar see events in their own time zone, regardless of what you set yours to.
Why you might need to change your time zone
You need to change your time zone if you move to a new location, travel for an extended period, or if Google Calendar is showing times that do not match your local clock. Google Calendar usually detects your time zone automatically based on your device or location, but that detection sometimes fails — especially if you use a VPN, travel frequently, or your device settings are out of sync.
If you notice that events appear at the wrong time, or if you create an event at 2 p.m. and it shows up at a different hour, a time zone mismatch is usually the cause. Changing your time zone fixes both the display and any new events you create going forward.
What happens to existing events when you change time zones
When you change your time zone, Google Calendar adjusts the display of all existing events to match your new location. An event that was scheduled for 3 p.m. in your old time zone will show at a different clock time in your new time zone, but the actual moment in time stays the same. If you had a meeting at 3 p.m. Eastern Time, it will display as 12 p.m. Pacific Time after you switch — the meeting itself has not moved.
This matters if you share calendars with people in other time zones. They will still see the event at the correct time in their own zone. The change only affects how the time appears on your screen.
Changing time zone for a single event instead of your whole calendar
If you want only one event to show in a different time zone, you cannot do that directly in Google Calendar. However, you can create the event with a note about the time zone, or you can add the time zone to the event title — for example, "Team meeting 2 p.m. EST" — so people know which zone you mean.
A workaround is to create the event in your current time zone, then temporarily change your calendar's time zone, create a copy of the event, and change your time zone back. This is cumbersome, so most people just note the time zone in the event details instead.
Time zone settings on shared and delegated calendars
If you share your calendar with others, each person sees events in their own time zone, not yours. Your time zone setting only affects what you see on your screen. When you invite someone to an event, Google Calendar sends them the time in their local zone automatically.
If someone else has delegated their calendar to you (given you permission to view and edit it), you see their events in your time zone, not theirs. If you need to see events in their original time zone, you would have to temporarily change your own time zone setting, which is why many teams include the time zone in the event title when they work across regions.
Troubleshooting time zone problems
If you changed your time zone but events still show the wrong time, first check that the change actually saved. Go back to Settings and confirm your time zone is listed correctly. If it is, try refreshing the page or closing and reopening Google Calendar.
If the problem persists, check your device's system time zone as well. Google Calendar sometimes reads from your device settings if there is a conflict. On a computer, check your operating system's time zone: on Windows, go to Settings > Time and Language > Date and Time; on Mac, go to System Preferences > Date and Time. Make sure both your device and Google Calendar are set to the same zone.
If you use a VPN, it can interfere with time zone detection. Try turning off the VPN temporarily, changing your time zone, and then turning the VPN back on. If you still have trouble, sign out of Google Calendar completely, clear your browser cache, and sign back in.
Frequently Asked Questions
Does changing my time zone affect events other people created and shared with me?
No. Those events display in your time zone on your calendar, but the actual event time does not change. If someone in New York invites you to a 9 a.m. meeting and you are in Los Angeles, you will see 6 a.m. on your calendar. Changing your time zone changes only how you see it, not when the meeting actually happens.
Can I set different time zones for different calendars?
No. Google Calendar uses one time zone for your entire account. If you manage multiple calendars, they all display in the same zone. You can add the time zone to event titles or descriptions if you need to track events across different regions.
What if my time zone is not in the dropdown list?
Type the name of your city or region into the search box in the time zone dropdown. Google Calendar includes time zones for most cities worldwide. If you still cannot find it, search for the nearest major city in your region — for example, if your town is not listed, search for the state capital or largest nearby city.
Will changing my time zone affect my Google Meet or Hangouts meetings?
No. The time zone setting in Google Calendar only affects how times display in the calendar itself. The actual meeting time does not change. Anyone invited to the meeting will see it at the correct time in their own zone, regardless of your calendar settings.
Do I need to change my time zone if I travel for a short trip?
Not necessarily. If you are traveling for a few days and returning home, leaving your time zone as your home location keeps your calendar accurate for events back home. If you are relocating permanently or staying somewhere for several weeks, changing your time zone prevents confusion about when local events occur.
