Day light saving

Share This
Back in India, people most of the time are not aware of the concept of Day light saving. In general, the span of the day having sunlight does not vary significantly over the year. So, this concept was never a requirement.

When an Indian move to other parts of the world like say European countries or America, they come across this concept.
The idea is to make maximum use of daylight. During the summer, the day could be as long as 16 hrs to 22 hrs depending on how close you are to the North pole while the winters have very short days.
So, in winter days, if your office timing is say 9 AM to 5PM, by the time you start from home to office and while you are leaving office back to home, its mostly dark outside. You only get to see daylight while you are in office and there is no time for doing external extra curricular activities.
In contrast during summer, if the timings of winters are followed, the day light is available say since 5.00 AM till 10.00 PM. If your office timing is still 9-5, you have 4hrs of daylight in the morning which is pretty much of no use leaving around 5 hrs in the evening for extracurricular activities.
So, instead if the clock is forwarded in summer by 1 hr, you start receiving daylight by around 6.00 AM while in the evening it lasts till 11.00PM.
By implementing daylight saving we shift one hour of daylight from morning to evening and so we have around 6 hrs of daylight in the evening instead of 5.

Another advantage of daylight saving as pointed out is, since people spend most of the time of evening either outside home or without the use of electricity for lights, there is less consumption of electricity.

In Europe, the daylight saving is implemented on the last sunday of March which this year happened on 25th of March. It will last for next 6 months till the last Sunday of October when it returns to the regular time.

Although Day light saving has its advantages, people don't like initial few days after it is implemented. The problem is the last sunday of March is reduced to 23 hrs. To quickly get used to the changed timing, one tries to sleep early. But the body is normally not used to sleep early so one ends up wasting time waiting for sleep. Next day, you are already late by 1 hour. Fortunately or say considering the inconvenience, next day is Sunday, you are pretty much relaxed with no rush to reach the office. But the day ends quickly and although you don't feel sleepy its already your bed time. Your body takes some to get used to this change.

Monday onwards another peculiar change you start observing is the lengthy evening. First few initial days it feels odd when you reach home,relaxed, already had a cup of tea and evening breakfast and still find proper daylight outside your window. Over the days,although, it changes to the point where you need to pull down the curtains to go to bed, your body gets used to it.

  In contrast in the other half of year when daylight saving is stopped on the last sunday of October, things are pretty relaxed. This time you have an extra hour to adjust to the changes. The last sunday of October is 25 hrs long. So whatever time you go to sleep, you always wake up one hour earlier than expected. You feel like day is going is passing very slow. You have more time in hand to take care of that day's business and still you have time to relax and enjoy.
In following days whereas days seems short when you go out of home for office and come back only in dark.

Some body put this picture on net that nicely  depicts the differences while waking up on two mornings.
