Daylight saving time (DST)

Whether you like it or not, on Sunday, March 12, at 2 a.m., we’ll do our yearly ritual of converting to Daylight saving time.

It’s less of a hassle now, though, because the majority of our laptops, smartphones, and DVRs adjust the time for us automatically. Microwaves and ovens are among the few household equipments that require manual adjustment unless you have smart appliances.

Who is responsible for DST, Daylight saving time? When did it first begin? Why is it observed by the US and more than 70 other nations? The solutions to those queries and more are provided here:

What is Daylight saving time?

The technique of moving the clock forward as the weather gets warmer and backward when it gets colder is known as Daylight saving time (DST).

By extending the amount of time we may be outside during the day, Daylight Saving Time aims to maximize the use of daylight.

The months that the clock is moved forward and backward in the Northern and Southern hemispheres are different.

How does Daylight saving time work?

It’s crucial to keep in mind that Daylight Saving Time varies slightly from country to country and that it is not observed in all time zones.

The Northern Mariana Islands, U.S. Virgin Islands, Puerto Rico, American Samoa, Guam, Japan, India, and China are a few examples.

The majority of states in the union move their clocks forward one hour on the second Sunday in March and back one hour on the first Sunday in November. Hawaii and Arizona, with the exception of the Navajo Nation, do not observe Daylight Saving Time.

Here are a few examples of how Daylight Saving Time is observed around the world:

  • Daylight saving time begins on the first Sunday in November and finishes on the third Sunday in February in non-equatorial Brazil.
  • The final Sunday in March at one in the morning, DST begins in the European Union. Ends on the final Sunday in October at the same time as Coordinated Universal Time.
  • DST in Germany begins on the final Sunday of March and concludes on the final Sunday of October.
  • Beginning on the last Sunday in March at 2 a.m. local time, the clock is advanced in Russia. The opposite occurs on the last Sunday in October at the same hour. The clock in Russia is already one hour ahead of standard time, thus during the summer there are actually two more hours of daylight.
  • Daylight Saving Time is observed throughout Israel and the surrounding region of Palestine, however, the exact time is determined annually. Sometimes the start and finish dates are different for Israel and the Palestinian Authority.
  • It is always Daylight Saving Time in Jordan.
  • DST begins in Australia on the final Sunday of October and concludes on the final Sunday of March. However, DST in Tasmania begins on the first Sunday in October and finishes on the same day that it does in New Zealand.

Who invented Daylight saving time?

You can thank British architect William Willett and New Zealand physicist George Vernon Hudson for the notion of Daylight Saving Time. Hudson suggested a 2-hour shift forward in October and a 2-hour shift back in March in a paper that he delivered to the Wellington Philosophical Society in 1895. Although there was enthusiasm in the concept, nothing ever came of it.

Independent of Hudson, British builder William Willett proposed eight-time changes annually in 1905: 20-minute time changes on each of the four Sundays in April and a 20-minute time change on each of the four Sundays in September.

Benjamin Franklin, the father of Daylight saving time (DST)?

Benjamin Franklin is credited with being the first to propose seasonal time change, according to many accounts. The American politician and inventor’s concept, nevertheless, can scarcely be regarded as being important to the advancement of modern DST. After all, there wasn’t even a clock adjustment. Franklin merely suggested that Parisians may reduce candle consumption by getting people out of bed earlier in the morning in a letter to the editor of the Journal of Paris headlined “An Economical Project for Diminishing the Cost of Light.” Franklin also meant it as a joke.

When did U.S. officially enact Daylight saving time?

With the passing of the Uniform Time Act in 1966, DST became a recognized national standard in the United States. States must either change their clocks at a specific time or maintain standard time all year round.

In an effort to use less energy, the federal government extended Daylight Saving Time in 2007. The law presently states that daylight saving time is used from the second Sunday in March through the first Sunday in November at 2 a.m.

Presently, Daylight saving time makes up around 65% of the year.

States are permitted by federal law to maintain standard time throughout the year, but they are not permitted to make daylight saving time a permanent fixture without prior consent from Congress.

What are the downsides of DST

Some contest the claim that it has energy-saving advantages. According to some research, the time switch reduces energy use for lights, but increases in heating and air conditioning outweigh these savings. It can also momentarily interfere with our sleep cycles.

Other negative health effects include an increase in headaches, heart attacks, and depression, according to several studies and research.
