About Daylight Savings End
The idea of daylight saving time (DST) was first proposed by Benjamin Franklin in 1784, but it was not widely adopted until the 20th century. The modern system of daylight saving time was first introduced by Germany and Austria-Hungary during World War I as a way to conserve coal. The practice was later adopted by other countries and is now observed in many parts of the world, although the start and end dates, as well as the amount of time shifted, can vary widely between countries and regions.
In the United States, daylight saving time is primarily regulated by the Uniform Time Act of 1966, which sets the dates for DST to begin on the second Sunday of March and end on the first Sunday of November. However, states and territories are free to exempt themselves from observing DST if they so choose.
