Did daylight saving time occur? Here’s why the clocks were set back an hour on Sunday.

 Did you appreciate the extra hour of sleep? Daylight saving time has officially come to an end.

Now is the perfect time to enjoy a pumpkin spice latte and take in the beautiful fall foliage. After an unusually warm end to summer and a milder-than-average fall, temperatures are set to drop. This week, several Texas cities may even experience their first freeze.

Here’s what you need to know about daylight saving time in 2024:

When Did Daylight Saving Time End?

Daylight saving time concluded at 2 a.m. on Sunday, November 3. We have returned to standard time.

When the clock struck 2 a.m., it reverted back to 1 a.m. Many devices, such as smartphones and computers, likely adjusted automatically, but non-smart devices like microwaves, car radios, and analog clocks probably need to be set manually.

Looking Ahead: When Does Daylight Saving Time Start Again?

In 2024, we set our clocks forward an hour on Sunday, March 10, and will fall back again on Sunday, November 3. In 2025, we’ll spring forward again on March 9 and fall back on November 2.

Since 2007, daylight saving time has begun on the second Sunday in March and ended on the first Sunday in November, following the Energy Policy Act of 2005. Prior to that, a 1986 law set the time changes for the first Sunday in April and the last Sunday in October. Between 1976 and 1986, clocks moved forward on the last Sunday of April, and in 1974 and 1975, daylight saving time began in January and February, respectively.

The U.S. first officially recognized daylight saving time in 1918 when President Woodrow Wilson signed the Standard Time Act into law.

What Does the End of Daylight Saving Time Mean?

With daylight saving time ending, mornings will be brighter, and evenings will get darker earlier. On the first Sunday of November, sunrise and sunset occur about one hour earlier compared to the first Saturday of the month.

For most Americans, except those in Arizona, Hawaii, and a few other locations, the end of daylight saving time means an extra hour of sleep. It also allows for more daylight in the mornings as we prepare for winter.

The Origins of Daylight Saving Time

Daylight saving time is known by various names, including daylight savings time and summer time (not to be confused with summertime). It involves moving clocks forward by one hour in warmer months and back by one hour in the fall. A helpful way to remember this change is "spring forward, fall back."

The concept originated during World War I, although Benjamin Franklin is sometimes credited with the idea due to a satirical letter he wrote in 1784 advocating for earlier rising. To conserve resources during the war, Germany and Austria first implemented daylight saving time in 1916, and the U.S. followed suit in 1918.

Though some view it as an outdated practice, the goal of daylight saving time is to make the most of natural daylight, which is particularly beneficial during the summer months. In the Northern Hemisphere, longer days are experienced from March to November, with the longest days occurring from June to August. In contrast, the Southern Hemisphere, such as Australia, has its shortest days during its winter months from June to August.

What’s Coming Up?

According to NOAA’s winter forecast, the winter solstice, marking the shortest day of the year in 2024, will fall on Saturday, December 21. As winter approaches, we can expect later sunrises and earlier sunsets, resulting in fewer hours of daylight overall, as the Northern Hemisphere tilts away from the sun.
