Daylight Saving Time (DST)—often colloquially called “saved time” or “daylight savings”—is the seasonal practice of setting clocks forward by one hour in the spring and turning them back one hour in the fall. The core objective is to shift an hour of daylight from the early morning to the evening, aligning standard human waking schedules with natural summer sunlight. The Mechanics of the Clock Shift
Spring Forward: Clocks move ahead one hour on the second Sunday of March, meaning 2:00 AM instantly becomes 3:00 AM. This results in losing an hour of sleep.
Fall Back: Clocks move backward one hour on the first Sunday of November, meaning 2:00 AM resets to 1:00 AM. This grants an extra hour of sleep.
Standard Time: The period between November and March when regions return to their geographically accurate time zones. Historical Origins What is Daylight Saving Time | Facts for Kids
