Daylight savings
time system is followed in mostly North American and European countries. But
why are we bound to it? Who disrupted our daily life for one day or two? Read
the facts and find your answer!
Modern Time was invented in Ancient Egypt
The ancient
Egyptians were the first or one of the first ancient civilizations to divide a
day into sections, so they could tell what time it was. They divided the day
into two 10 hour segments. They then added one hour at each end of the 10
hours, one for dawn and one for the twilight. Thus, they created 24 hour
standard system.
But the credit
of division of an hour goes to the Babylonians. They used sexagesimal (counting
in 60s) system which was derived from their predecessors- the Sumerians who
used it in 3500 B.C.
Later ancient
Greco- Egyptian mathematician Claudius Ptolemy divided the hour further into
seconds. However it was until 16th century that mechanical clocks
were invented and modern timekeeping was born.
Ancient Romans practised DST!
Ancient Romans
were familiar with hours and minutes but not with seconds. They did not fix
their schedules to the clock the way we do today, but they did adjust their
schedules according to the sun.
During summers,
they used to divide daylight into twelve hours regardless of daytime, so that
each daylight hour was longer during summer. Unlike Egyptians who used Shadow
clocks to trace time, the ancient Romans used Water clocks.
To adjust with
DST, Romans would use water clocks of different amounts for different months of
year.
Benjamin Franklin gave the Idea of DST
In 1784,
Benjamin Franklin wrote a letter to the editor of journal of Paris. He outlined
the need to align the clock according to sun set and sun set. The essay was
meant to be a joke. He further suggested that Parisians could save on the cost
of candles if they got out of bed earlier in the morning.
It is said that
he got this idea after riding his horse one summer morning and noticing how
many blinds were still down, which was pointing towards the wastage of
sunlight.
DST became mandatory during WWI
During World War
1, in order to save coal for war efforts, Germany and several other European
countries enforced the DST system. They believed DST was a way of reducing the
use of electricity. But it is still controversial as there is hardly any proof
that says that DST saves or reduces electricity.
After World War
II, a lot of chaos was caused in America as some cities refused to stick with
DST. Then 1966, the uniform time act was enforced which standardised DST from
last Sunday in April to the last Sunday in October.
Different times for different countries
Not everyone
changes the clock on same date. Even in Canada, many provinces don’t follow
DST. Israel usually changes the clock on the last Sunday in October.
Brazil on the
other hand changes its time on third Saturday in October.
More time for Trick or Treat!
DST is a
blessing for candy makers. Longer amount of daylight in the fall means more
time for kids to go trick or treating on Halloween. Candy makers enjoy their
sales as kids get extra hour of daylight to collect candy.
Barbeque industry
also has a lot of stake. In 1986, when U.S. added extra month of DST, it was
worth $100M in extra sales of grills and charcoal briquettes.
Everyone won’t be on time!
People often get
confused during DST. They forget to either fall back or spring forward. So it
eventually results in them getting late or coming early at their workplace.
Alert! Exam Scores can be Messed
It’s a warning
for high school students or teenagers preparing for entrance exams. The change
of time can mess up sleep schedules of teens causing them to perform poorly on
college exams. SAT tests are administered after DST. So beware!
Health problems and accidents increase
Lack of sleep
can have unfortunate effects. A Swedish study reveals the risk of having heart
attacks increases in first three weekdays after switching to springing forward.
Losing one hour
of afternoon daylight after setting the clocks back to standard time can
trigger mental illness, including bipolar disorder and seasonal effective
disorder also called winter depression.
Subtle changes
in sleep patterns and circadian rhythms can alter human alertness which can
cause fatal car accidents.
People who work
at physically taxing jobs such as miners have been shown to experience more
frequent and severe workplace injuries at the onset of daylight saving time in
the spring.
The researches
attribute the injuries to lack of sleep, which might explain why the same
effect did not pop up in the fall when workers gained an hour of sleep.
Longer cyber loafing
Cyber loafing is
a slang word for surfing for entertainment during work hours. It can cause the
companies thousands of salary wages flushed down the internet tube.
Lack of workday
motivation and focus caused due to lack of sleep in the spring may cause this
increase.
People want it repealed
DST favouring
folks often argue that DST is energy conserving, promotes outdoor leisure
activity during summer nights, which helps in psychological health and reduces
accidents. Urban people usually support DST.
But according to
farmers living in the rural areas, the natural biorhythm of animals and humans
is disrupted by this system. National geographic argues that actual energy
savings benefits are inconclusive.
Don’t become
victim of DST change. Just remember
Spring: forward
Fall: back.
