It may still feel like summer, but fall, cooler weather and the end of this year's daylight saving time is drawing nearer.
At 2 a.m. Nov. 6, you will need to set your clocks back one hour to 1 a.m., meaning we will "fall back" and gain an extra hour of sleep.
In March, we do the opposite – setting our clocks forward one hour and losing an extra hour of sleep.
Ahead of the day observed biannually in most states, here's what to know.
Why do we gain an hour in November?
We gain an hour in November (as opposed to losing an hour in the spring) to accommodate for more daylight in the mornings. When we "spring forward" in March, it's to add more daylight in the summer evenings.
In the Northern Hemisphere, the autumnal equinox is Sept. 22, marking the start of the fall season.

Why do we have daylight saving time?
In 1966, Congress passed the Uniform Time Act, standardizing the length of daylight saving time, which runs from March to November.
Daylight saving time begins on the second Sunday of March each year and ends on the first Sunday of November.
The Department of Transportation said daylight saving time saves energy, prevents traffic injuries and reduces crime. The DOT oversees time zones and the uniform observance of daylight saving time because the railroad industry first instituted time standards.
What states have gotten rid of daylight saving time?
Not all states and U.S. territories participate in daylight saving time.
Hawaii and Arizona (with the exception of the Navajo Nation) do not observe daylight saving time, and neither do the territories of American Samoa, Guam, the Northern Mariana Islands, Puerto Rico and the U.S. Virgin Islands.
Last year, the U.S. Senate unanimously approved a bill called the "Sunshine Protection Act" that would make daylight saving time permanent starting in 2023. The measure has not yet passed in the U.S. House of Representatives, nor has it been signed into law by President Joe Biden.

Who created daylight saving time?
Benjamin Franklin is often credited with first proposing daylight saving in his 1784 essay, "An Economical Project." The idea wasn't seriously considered, however, until more than a century later when William Willetts, a British builder, fiercely advocated for it.
The current daylight saving time format was proposed in New Zealand by entomologist George Hudson.
In 1895, he recommended a two-hour time change because he wanted to have more daylight after work to go hunting for bugs in the summer.
When does daylight saving time begin in 2023?
In 2023, daylight saving time will begin at 2 a.m. on Sunday, March 12 and will end for the year at 2 a.m. on Sunday, Nov. 5.
