“Saved time” most commonly refers to Daylight Saving Time (DST), the seasonal practice of setting clocks forward by one hour in the spring and back one hour in the autumn. This shift moves an hour of daylight from the morning to the evening to make better use of natural sunlight during warmer months. How It Works
The system relies on a simple concept: “Spring forward, fall back.”
In the Spring: Clocks advance by one hour (usually on the second Sunday of March in North America). This causes you to “lose” an hour of sleep, but it extends evening daylight.
In the Fall: Clocks move backward by one hour (usually the first Sunday of November), returning to Standard Time and giving you that hour back. History and Origins
