Daylight Saving Time (DST)—often referred to colloquially as “saved time” or daylight savings—is the global practice of advancing clocks ahead by one hour during the warmer months of the year so that evening daylight lasts longer. The Core Schedule
In the United States, DST follows a standard timeline mandated by the U.S. Naval Observatory and federal law:
Spring Forward: Clocks shift ahead 1 hour on the second Sunday in March at 2:00 a.m..
Fall Back: Clocks return back 1 hour to standard time on the first Sunday in November at 2:00 a.m.. Why It Was Created
Energy Savings: Shifting daylight hours originally aimed to reduce the need for artificial evening lighting.
Wartime Fuel Conservation: Germany first implemented DST in 1916 during World War I to optimize coal and fuel, and the U.S. followed in 1918.
Economic Boost: Studies show people spend more money at retail businesses when there is daylight after work or school. The Health and Safety Impact 7 Things to Know About Daylight Saving Time | Johns Hopkins
