How to Turn On or Off Adjust for Daylight Saving Time Automatically in Windows 11
Adjust for Daylight Saving Time automatically in Windows 11 keeps your PC clock accurate when time shifts forward or back. Daylight Saving Time is the twice-yearly practice of moving clocks by one hour to make the most of evening daylight during warmer months.
About 70 percent of countries worldwide skip this time change, so Windows 11 lets you turn the automatic update on or off depending on your local rules. You control this setting through the Date & Time menu in your main system settings.
Go to Settings , then Time & language, and finally Date & time. Toggle “Adjust for daylight saving time automatically” on or off. This setting allows Windows 11 to manage clock changes for DST.
Why Change This Setting?
Operating systems default to automatic updates, but regional exceptions or personal preference might require manual control.
