Daylight saving time (DST)Â is the practice of advancing clocks (typically by one hour) during warmer months so that darkness falls at a later clock time. The typical implementation of DST is to set clocks forward by one hour in the spring (“spring forward”) and set clocks back by one hour in autumn (“fall back”) to return to standard time. As a result, there is one 23-hour day in late winter or early spring and one 25-hour day in the autumn.
Daylight saving time implementation varies from country to country. Some countries may not observe daylight saving time (DST), whereas other countries may change the start dates and end dates for daylight saving time every year. This article describes how to update Windows to use the latest DST and global time zone rules.
Many applications and cloud services reference the underlying Windows operating system for daylight saving time (DST) andÂ time zoneÂ (TZ) information.
Windows 11 will automatically adjust the time for daylight saving time by default, but you can turn this setting on or off anytime you want.
This tutorial will show you how to turn on or off automatically adjust clock for daylight saving time (DST) for all users in Windows 11.
