DAYLIGHT SAVING TIME ENDS: ARE THERE HEALTH RISKS?
Here are 10 little-known facts about Daylight Saving Time.
3rd month, 11th month – Daylight Saving Time happens two times each year, once in March (spring) and once in November (fall).
The spring Daylight Saving Time adds an hour, so “there is one less hour in the day,” while the fall Daylight Saving Time subtracts an hour, so “there is an extra hour in the day,” according to the U.S. Department of Commerce’s National Institute of Standards and Technology.
2nd Sunday at hour 2 – The two dates for Daylight Saving Time change each year because they are implemented on the second Sunday of March and the second Sunday of November.
Daylight Saving Time happens at 2 a.m. each time, according to the National Institute of Standards and Technology.
For spring Daylight Saving Time, clocks jump forward to 3 a.m. once it strikes 2 a.m. local time, which skips 2 a.m. altogether.

For fall Daylight Saving Time, the opposite happens, and clocks jump backward to 1 a.m. once it strikes 2 a.m. local time, so the hour is repeated before it moves in chronological order again.
1916 – The first instance of Daylight Saving Time happened in Germany on April 6, 1916, during World War I, according to the Textual Records Division of the U.S. National Archives and Records Administration.
In a blog post, the Textual Records Division reported that the German Bundesrat’s Federal Council passed an order that instructed citizens to change their clocks by adding “an hour of daylight to the day during the months of May through September.”
1918 – Congress passed the Standard Time Act of 1918, according to a Daylight Saving Time article published by the U.S. House of Representatives’ History, Art & Archives website.
The Standard Time Act of 1918 was the country’s first nationwide daylight-saving law.
“The act, which built off an earlier campaign by railroad companies to synchronize their schedules in North America, established five time zones across the continental United States and Alaska and, importantly, mandated that clocks be advanced one hour on the last Sunday in March and set back one hour on the last Sunday in October,” the History, Art & Archives wrote in its report.

1966 – The Uniform Time Act of 1966 was signed into law on April 13, 1966, by President Lyndon B. Johnson, according to the U.S. House of Representatives’ History, Art & Archives.
“Although the law would be amended several times in the coming decades, the Uniform Time Act of 1966 remains a major foundation of our system of timekeeping,” the History, Art & Archives wrote.
71 – Only 71 countries observe Daylight Saving Time, according to Time and Date, a Norwegian-owned time zone and global clock website.
Daylight Saving Time is reportedly still used in eight countries in North America, two countries in South America, seven countries in Asia, two countries in Africa, three countries in Oceania (Australia and the Pacific Islands) and 49 countries in Europe.
