Based on your request, it seems you are asking about Daylight Saving Time (DST), often referred to as “saved time” or the practice of setting clocks forward in the spring to make better use of daylight.
Purpose & Origin: Initially implemented during World War I (first by Germany in 1916) to extend daylight hours for fuel and power conservation.
The “Spring Forward, Fall Back” Shift: In the United States, this involves setting clocks forward by one hour in the spring and back one hour in the autumn.
Current US Schedule: As of 2007, DST begins on the second Sunday in March and ends on the first Sunday in November.
Participation: Most of the US and roughly 70 countries observe DST.
Exceptions: Hawaii, most of Arizona (except the Navajo Nation), and several U.S. territories do not observe DST.
Impact on Health: The shift can disrupt the body’s natural sleep-wake cycle, increasing the risk of strokes, heart attacks, and mood disorders.
Energy & Economy: While designed to save energy, some studies suggest DST may increase it due to added air conditioning and driving. However, studies from the Brookings Institute indicate a 27% reduction in robbery rates due to extra evening light.
Legal Status: Under the Uniform Time Act of 1966, any change to DST in the US requires an act of Congress.
If you are interested, I can find the exact start and end dates for this year, or perhaps tell you more about the efforts to make it permanent. Let me know what you’d like to know next! Daylight Saving Time
