You Won’t Believe How Time Change Swaps Your Clock Instantly — What Happens When Daylight Saving Hits? Every year, millions of devices automatically shift forward or backward by one hour during daylight saving time (DST) changes — but have you ever wondered how this time shift actually happens and why it feels so sudden? You won’t believe how seamlessly and instantly your clock swaps clocks each November and March — without any manual input in most modern devices. ### What Triggers Time Change? The Automatic Clock Adjustment Daylight saving time works by shifting clocks forward in spring (usually the second Sunday in March) and backward in fall (first Sunday in November). Thanks to built-in automation in smartphones, computers, smartwatches, and smart home devices, your devices update time automatically — instantaneously, often in under a second.
