Daylight Saving Time (DST) is the practice of advancing clocks forward by one hour during the warmer months so that darkness falls at a later clock time. 💡 Core Mechanics
Spring Forward: Clocks move ahead one hour on the second Sunday in March, shifting evening light later but causing a temporary loss of sleep.
Fall Back: Clocks return to Standard Time on the first Sunday in November, granting an extra hour of sleep but bringing earlier darkness.
Exemptions: In the United States, Hawaii, most of Arizona, and various territories opt out of the system entirely. 📜 Historical Origins
The Concept: New Zealand entomologist George Hudson proposed it in 1895 to gain more after-work daylight for collecting insects.
Implementation: Germany first adopted the practice in 1916 during World War I to conserve fuel and coal.
Standardization: The United States standardized the schedule via the Uniform Time Act of 1966. Daylight Saving Time
