Here's why we're setting our clocks back this weekend as Daylight Saving Time 2019 ends

This weekend, remember to change your clocks back one hour before bedtime Saturday night on Nov. 2. Daylight Saving Time officially ends at 2 a.m. Sunday, Nov. 3.

SAN DIEGO — Daylight Saving Time officially comes to an end this weekend… that means we get to “Fall Back” and get an extra hour of sleep!

This weekend, remember to change your clocks back one hour before you go to sleep Saturday night on Nov. 2. Daylight Saving Time officially ends at 2:00 a.m. Sunday, Nov. 3. Most smartphones will adjust automatically.

If you’re not a fan of standard time, Daylight Saving Time begins again on Sunday, March 8, 2020.

Here's the how and why of Daylight Saving Time...

Daylight Saving Time first became popular two years into World War I in the year 1916, when Germany and Austria mandated the time change in order to minimize the use of artificial light and to save fuel for the war. Other countries quickly followed this action.

In the United States, the concept of daylight saving was adopted in The Standard Time Act of 1918 , also known as the Calder Act. This was the first U.S. federal law implementing both Standard time and Daylight saving time, and allowed the Interstate Commerce Commission to define time zones. Part of the act was repealed one year later, and from there it was up to smaller, local jurisdictions to decide whether or not to observe the two different time periods.

Through the last century, numerous changes have been made to the U.S. use of time zones, standard time and daylight saving time. In World War II, President Franklin D. Roosevelt implemented a year-round DST that was commonly known as "War Time".

The Energy Policy Act of 2005 allowed states to 'opt out' of the time change. Arizona and Hawaii do not use DST, as well as other U.S. territories. For the rest of us, Daylight Saving Time begins at 2:00 a.m. on the second Sunday of March and ends at 2:00 a.m. on the first Sunday of November.

So don't forget to "Fall Back" this Saturday night -- Standard Time begins this Sunday at 2:00 a.m.!
