What Is Daylight Saving Time?
Daylight saving time (DST) is the period between spring and fall when many people change their clocks forward one hour.

What is daylight savings time?
Daylight saving time ( DST ), also known as daylight savings time or daylight time (the United States and Canada ), and summer time ( United Kingdom, European Union, and some others), is the practice of advancing clocks (typically by one hour) during warmer months so that darkness falls at a later clock time.
Why is daylight saving time pushed an hour later?
Since daylight saving time creates the illusion of the sun rising and setting one hour later on the clock, but does not add any additional daylight , the already later sunrise times under standard time are pushed an hour later on the clock with daylight saving time. Late sunrise times can become unpopular in the winter months which essentially forces workers and schoolchildren to begin the day in darkness. In 1974 following the enactment of the Emergency Daylight Saving Time Act in the United States, there were complaints of children going to school in the dark and working people commuting and starting their work day in pitch darkness during the winter months. The complaints led to the repeal of the act in October 1974 when standard time was restored until February 23, 1975. In 1976, the United States returned to the schedule set under the Uniform Time Act of 1966. In 1971, year-round daylight time in the United Kingdom was abandoned after a 3-year experiment because of complaints about winter sunrise times. The same complaints also led to Russia abandoning DST and instituting standard time year round in 2014.
How did the ancient civilizations adjust their daily schedules?
Ancient civilizations adjusted daily schedules to the sun more flexibly than DST does, often dividing daylight into 12 hours regardless of daytime, so that each daylight hour became progressively longer during spring and shorter during autumn. For example, the Romans kept time with water clocks that had different scales for different months of the year; at Rome's latitude, the third hour from sunrise ( hora tertia) started at 09:02 solar time and lasted 44 minutes at the winter solstice, but at the summer solstice it started at 06:58 and lasted 75 minutes. From the 14th century onwards, equal-length civil hours supplanted unequal ones, so civil time no longer varied by season. Unequal hours are still used in a few traditional settings, such as some monasteries of Mount Athos and all Jewish ceremonies.
How many hours is DST?
The typical implementation of DST is to set clocks forward by one hour in the spring (" spring forward") and set clocks back by one hour in autumn (" fall back") to return to standard time. As a result, there is one 23-hour day in late winter or early spring and one 25-hour day in the autumn . Daylight saving time regions:
When was daylight saving invented?

What is the clock called in winter?
In most countries that observe seasonal daylight saving time, the clock observed in winter is legally named "standard time" in accordance with the standardization of time zones to agree with the local mean time near the center of each region.
Why is DST important?
One of the aims of DST is to make sure that people's active hours coincide with daylight hours so that less artificial light is needed . This makes less sense close to the equator, where the amount of daylight does not vary much in a year, or near the poles, where the difference between winter and summer daylight hours is very large.
What are the effects of DST?
Con: Can Make People Sick 1 Studies link the lack of sleep at the start of DST to car accidents, workplace injuries, suicide, and miscarriages. 2 The early evening darkness after the end of the DST period is linked to depression. 3 The risk of suffering a heart attack is also increased when DST begins. However, the extra hour of sleep we get at the end of DST has, in turn, been linked to fewer heart attacks.
Why do we set the clocks forward one hour in spring?
Setting the clocks forward one hour in spring does not create more daylight, but it does change the time (on the clock) the Sun rises and sets. So, when we spring forward an hour in spring, we add one hour of natural daylight to our afternoon schedule. Proponents of DST argue that longer evenings motivate people to get out of the house.

Studies link the lack of sleep at the start of DST to car accidents, workplace injuries, suicide, and miscarriages. The early evening darkness after the end of the DST period is linked to depression. The risk of suffering a heart attack is also increased when DST begins.
Does daylight saving energy save energy?
Con: Doesn't Save Energy. A century ago, when DST was introduced, more daylight was a good thing because it meant less use of artificial light and more energy savings. Modern society, with its computers, TV-screens, and air conditioning units, uses more energy, no matter if the Sun is up or not.

However, at latitudes between these extremes, adjusting daily routines to the shifting day length during summer may indeed help to save energy. A German analysis of 44 studies on energy use and DST found a positive relationship between latitude and energy savings.
Does changing the time make you sick?
Con: Can Make People Sick. Changing the time, even if it is only by one hour, disrupts our body clocks or circadian rhythm. For most people, the resulting tiredness is simply an inconvenience. For some, however, the time change can have more serious consequences to their health.
