Daylight Saving Time

Just today I'm so surprise when my hubby told me that we need to adjust an hour advance of our time. He says, it's called DST (Daylight Saving Time). Well, we don't have like this in the Philippines. He says that if it alamost Spring time time changes. And one more thing, on Fall, time needs to be late an hour. My golly, why?? So, I ask my hubby about it. Then he explain to me that Daylight Saving Time gives us the opportunity to enjoy sunny summer evenings by moving our clocks an hour forward in the Spring.



And here are some reasons why they have this DST:

1. Fewer traffic accidents:Several studies in the United States and Great Britain have found that the daylight shift that comes with Daylight Saving Time and Summer Time reduces net traffic accidents and fatalities by close to one percent. An increase in accidents during the darker mornings of fall is more than offset by the evening decrease in accidents.

2. Energy conservation : Daylight Saving Time and Summer

a.)Time save energy:Outdoor activities save energy.Most people plan outdoor activities during the extra daylight hours of Summer Time. Because people are home fewer hours during the "longer" days of spring and summer, they don't turn on appliances and lights, and less electricity is used. Some argue, however, that the savings in electricity is offset by an increase in the use of gasoline.

b.)Morning electricity usage offset by DST : In the summer, people who rise before the sun rises use more energy in the morning than if Daylight Saving Time was not in effect. However, although 70% of Americans arise before 7:00 a.m., this energy usage from having less sunlight in the morning is more than offset by the savings of energy that results from more sunlight in the evening.

c.) Lighting and small appliances : Energy use and the demand for electricity for lighting homes is directly related to the times when people go to bed at night and rise in the morning. In the average home, 25% of electricity is used for lighting and small appliances, such as home entertainment centers. A good percentage of energy consumed by lighting and appliances occurs in the evening when families are home. By moving the clock ahead one hour, the amount of electricity consumed each day decreases.

3. People like it : A poll conducted by the U.S. Department of Transportation indicated that Americans like Daylight Saving Time because "there is more light in the evenings/can do more in the evenings." A 1976 survey of 2.7 million citizens in New South Wales, Australia, found that 68% liked Summer Time. Indeed, some say that the primary reason that Summer Time is a part of many societies is simply because people like to enjoy long summer evenings.

4. Fewer violent crimes: A study by the U.S. Law Enforcement Assistance Administration found that crime was consistently less during periods of Daylight Saving Time than during comparable standard time periods. Data showed violent crime down 10% to 13%. It is clear that, for most crimes where darkness is a factor such as muggings, there are many more incidents after dusk than before dawn, so light in the evening is most welcome.



So,DST is stealing one hour of sleep but giving us in return one extra-hour of light in the afternoon. What is the point in all this, you might wonder, and the answer is very simple: TO SAVE ENERGY.
