Daylight Saving Time - “Spring forward, Fall back”

Daylight Saving Time
(or summertime as it is called in many countries) is a way of getting more light out of the day by advancing clocks by one hour during the summer. During Daylight Saving Time, the sun appears to rise one hour later in the morning, when people are usually asleep anyway, and sets one hour later in the evening, seeming to stretch the day longer.

The reason DST works is because its saves energy due to less artificial light needed during the evening hours—clocks are set one hour ahead during the spring, and one hour back to standard time in the autumn. Many countries observe DST, and many do not.

Note: Between March–April through September–November, it is summer in the northern hemisphere, where many countries may observe DST, while in the southern hemisphere it is winter. During the rest of the year the opposite is true: it is winter in the northern hemisphere and summer in the southern.

Benjamin Franklin first suggested Daylight Saving Time in 1784, but it was not until World War I, in 1916, when it was adopted by several counties in Europe that initially rejected the idea.

Daylight Saving Time begins On Sunday, March 14, 2010 at 2 a.m., Daylight Saving Time begins in the United States.The phrase “Spring forward, Fall back” is best and it will help people understand that during spring the keep the clock one hour ahead and in fall they keep the clock 1 hour back to set it in standard time.

Use of Day light Saving

The change to Daylight Saving Time allows us to use less energy in lighting our homes by taking advantage of the longer and later daylight hours. During the eight-month period of Daylight Saving Time, the names of time in each of the time zones in the U.S. (map) change as well. Eastern Standard Time (EST) becomes Eastern Daylight Time, Central Standard Time (CST) becomes Central Daylight Time (CDT), Mountain Standard Time (MST) becomes Mountain Daylight Time (MDT), Pacific Standard Time becomes Pacific Daylight Time (PDT), and so forth.

INDIA SHOULD observe DST (Daylight Saving Time)
and divide in two or maybe three time zones. It will help people to understand the value of time wasted in morning and working late in after hours.

Daylight saving time (DST) is the convention of advancing clocks as afternoons have more daylight and mornings have less. The savings come from reduced electricity usage in the evening – when lights don’t need to be switched on until later.

To facilitate this, clocks are adjusted forward one hour near the start of spring and are adjusted backward in autumn. This method is widely used in Western countries as a way to save energy. It is believed that this act of advancing the clocks by an hour during the summertime saves considerable energy/electricity, variously put at one per cent, if not more. We will never know what benefits, until we try this.

Shame! We have to be still thinking of this while the rest of the world has it already. Our system is kind of chaotic, but we do have an order and a rhythm to that chaos.
