How to Change the Time Zone in Windows 10

To change the time zone in Windows 10, go to Settings > Time & Language > Date & time. Turn off Set time zone automatically, then choose your time zone from the Time zone list. The clock updates right away.

You can also right-click the clock on the taskbar and select Adjust date/time to get to the same page.

Applies to: Windows 10. Microsoft ended Windows 10 support on October 14, 2025, so a PC without Extended Security Updates no longer receives security fixes; that program runs until October 12, 2027.

Change the time zone in Settings

1. Press Windows + I and select Time & Language > Date & time.
2. Turn off Set time zone automatically.
3. Select your zone from the Time zone list.

If the Time zone list is grayed out, Set time zone automatically is still on. For example, see how to set Philippine time in Windows 10.

Let Windows set it automatically

Turn on Set time zone automatically. Windows uses your location to choose the zone, which is handy if you travel. It needs location services: go to Settings > Privacy > Location and make sure location is on.

Change it in Control Panel

1. Search Start for Control Panel and open it.
2. Select Clock and Region > Date and Time.
3. Select Change time zone, choose your zone, and select OK.

Change it with a command

Open Command Prompt as an administrator and use the tzutil command:

• tzutil /g shows your current time zone.
• tzutil /l lists every time zone name.
• tzutil /s "Pacific Standard Time" sets a new zone. Use the exact name from the list.

To turn off daylight saving time for a zone, add _dstoff to its name, for example tzutil /s "Pacific Standard Time_dstoff".

In PowerShell, the same jobs use these commands:

• Get-TimeZone shows the current zone.
• Get-TimeZone -ListAvailable lists every zone with its Id.
• Set-TimeZone -Id "Pacific Standard Time" sets a new zone.

Daylight saving time

In Settings > Time & Language > Date & time, keep Adjust for daylight saving time automatically turned on. Windows then changes the clock on the right dates for your zone.

If the time is still wrong

• Check the zone first. A clock that’s off by exactly one or more hours usually means the wrong time zone.
• Sync the clock: under Synchronize your clock, select Sync now. This needs an internet connection.
• Turn on Set time automatically so Windows keeps the time accurate.
• If the time resets every time you start the PC, the small battery on the motherboard (CMOS battery) may be dying.
• On a work or school PC, your organization may control the time zone.
• Set time zone automatically is grayed out or wrong: it uses your location. Turn on Settings > Privacy > Location, or set the zone by hand.
• Your zone’s rules changed: when a country changes its time zone or daylight saving dates, Microsoft sends the fix through Windows Update. Install the latest updates.

Frequently asked questions

Does changing the time zone change file dates?

No. Files keep their real timestamps, and Windows shows them in your new time zone.

Can I show clocks for other time zones?

Yes. In Control Panel > Clock and Region > Date and Time, open the Additional Clocks tab and add up to two more clocks.

How do I change the time zone in Windows 11?

Windows 11 has its own time zone instructions.

Will my calendar events move?

Events keep the same real-world time. Outlook and the Calendar app show them in your new time zone, so a 9:00 a.m. meeting in New York shows as 6:00 a.m. if you switch to Pacific time.

Related: setting the date and time or syncing the clock with a time server, and changing the date format to something like dd/MM/yyyy.

Microsoft covers all three settings in Set time, date, and time zone settings in Windows.
