The time if the year has come, when 70 countries in the world shift their clocks forward (or backwards, according to their time zones). For this year, the Daylight Saving Time starts this Sunday morning. This would be a welcome to another hour of the day in the summer routine and obviously sacrifice to one-hour sleep at night. But why such a thing is in practice? Those of you who don’t know, this is Daylight Saving Time.
What is Daylight Saving Time?
Daylight Saving Time adds another hour during the summer while making the days shorter in the winter months. It is shifting the clocks to adjust the daylight hours during the day. Hence, the clock is shifted forward or backwards an hour to do so. About 70 countries in the world follow this routine. The countries in the northern hemisphere shift their clocks one hour ahead towards the end of March or early April. In late September or early October, they are set back one hour. Contrastingly, in the southern hemisphere, the reverse occurs.
The act of doing so or at least the theory to do so can be traced back a hundred years ago. In 1895, the New Zealand Entomologist George Hudson made the earliest known proposal for a time shift. The idea was well received in the Wellington philosophical society but it didn’t catch on. In 1905, a similar idea was presented by a builder William Willer and gave the bill in the parliament yeat after year until the day of his death in 1915. Churchill backed Willer’s idea. The issue was then revised again throughout the world many times but it was not applied nationwide until the early 20th century in Germany.
During the world war one, Germans were looking for a way to save energy and money in the most effective way possible. They decided that more daylight was the answer. Hence, became the first country to enact Daylight Saving Time. Since then, many laws have been instated for the implementations of Daylight Saving Time and have become a common practice in the united states. But many states can opt out such as Hawaii and Arizona. Some states are considering doing away with it. In Australia, 3 out of 8 states and territories do not practice Daylight Saving Time.
Is Daylight Saving Time really saving energy?
While the Daylight Saving Time was originally implied to add an extra hour in the day and cut off the usage of the artificial light, the critics say that it no linger save energy. Researchers and the government officials are re-evaluating the need for implying Daylight Saving Time.
In 2008, research was published that gave the statistics of energy consumption before and after the implementation of Daylight Saving Time in Indiana. The data reveal that there is actually a rise in 1% of residential energy usage. 80% of the globals population do not accord with the Daylight Saving Time.
Human Health and Daylight Saving Time
Rising in the 1% of energy consumption is not the end. The to and from the shift in an hour of the day Daylight Saving Time directly affects the sleeping pattern. This links to the increased rate of heart attacks and automobile fatalities.
