On Sunday the clocks ‘fall back’ one hour

play

We’re still a few days away from an extra hour of sleep! Fall is in the air, pumpkin spice lattes are back, and temperatures will start to cool…eventually.

As the days get shorter – and colder – and the sun rises later and sets earlier, many look forward to another sign of the season: when the clocks go back an hour. Here’s what you need to know about daylight saving time in 2024.

When does time change? When is summer time 2024?

Daylight saving time will end in 2024 2 a.m. on Sunday, November 3. That will return us to standard time and end Daylight Savings Time (DST).

When the clock reaches 2 a.m. local time, it moves back one hour to 1 a.m. Many devices, such as phones and computers, will automatically switch to standard time, but non-smart devices, such as microwave ovens and some car stereos, as well as any clock with hands will likely need to be changed manually.

When does daylight saving time start?

In 2024 we moved an hour further Sunday March 10. We’ll do it again next year Sunday March 9, 2025 and fall back an hour November 2, 2025.

Since 2007, daylight saving time begins on the second Sunday in March and ends on the first Sunday in November, as mandated by the Energy Policy Act of 2005. Before that, a 1986 law placed the time changes on the first Sunday in April and the last Sunday in October , according to the Department of Astronomical Applications. Between 1976 and 1986, the clocks went forward on the last Sunday in April. In 1974 and 1975, daylight saving time started in January and February respectively.

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

What does daylight saving time mean?

The end of summer time means that there is more light in the morning and that it gets dark earlier in the evening. Sunrise and sunset will be about an hour earlier on Sunday, November 3 than on Saturday, November 2.

For most Americans, except those in Arizona, Hawaii and a handful of other places, the end of daylight saving time means an extra hour of sleep on November 5. It also helps the country get more daylight in the morning in preparation for winter. .

How did daylight saving time start?

Daylight saving time (DST) goes by a variety of other names: daylight savings time, daylight time, daylight saving time (not to be confused with summer). It refers to the practice of moving the clock forward one hour during the warmer months of the year, then turning it back an hour in the fall.

One way to remember the pattern: “spring forward, fall back.”

The idea dates back to World War I, although some credit Benjamin Franklin with daylight saving time because of a satirical letter he wrote in 1784 in which he wrote, “Every morning, as soon as the sun rises, let all the bells in every church ring.” : and if that is not enough, let cannons be fired in every street to effectively wake up the sloths.

To maximize resources for the war, Germany and Austria introduced the first daylight saving time in 1916. The US did the same in 1918. An outdated idea, some say.

The general idea of ​​daylight saving time is to maximize the use of natural daylight, according to the Almanac. This always happens around the summer months. As the Earth moves around the sun and is tilted on its axis, certain parts of the world experience longer days during certain months. For those in the Northern Hemisphere, such as the US, these longer days run from March to November, with June to August seeing the longest days.

For those in the Southern Hemisphere, such as Australia, the seasons are reversed: June through August are the winter months and are therefore the shortest of the year.

When is the shortest day of the year 2024?

The shortest day of the year is the first day of winter or winter solstice. This will take place in 2024 Saturday December 21.

The sunrise will occur later, and the sunset will become earlier and earlier as we reach winter, and there are fewer hours of daylight in general; the tilt of the earth means that the northern hemisphere points away from the sun.
