Even in the late 70s people were already adjusting their clocks for daylight savings time. Since it has been practices for many years now, we tend to automatically reset our clocks on those two special appointed days even without knowing why.
Daylight savings time was born to save the sunlight. It keeps the daylight when w wants it during the time when we are at work or children are in school. In temperate regions, the variation of daylight versus darkness throughout the season is very great so they practice daylight savings time.
The necessity of the practice is being questioned by a lot of people today. People actually cannot understand what the difference is if it the run rises at 7 am rather than 8 am. Daylight savings time was implemented primarily to conserve energy and not for same conveniences that will be for our good.
Electricity consumption is actually reduced with daylight savings time since we usually turn on electricity when the sun has gone down. If the time between sunset and your bedtime is near then you energy consumption will be less than if the sun sets long before your bedtime.
Most of us have a set bedtime. So, if we try to move the sunset an hour later, a person will need to use less energy in the summer since he does not need to keep the lights on long just because it is dark outside if he is in bed.
Since it takes long for the sun to rise in winter, morning light is important. The summer days are longer and people wake up after sunrise. During winter, people wake up after the sunrise if the time of the sunrise is artificially changed by daylight savings time.
You can have more outdoor activities when there is daylight savings time. With daylight savings time, even during the winter, people can still have a great time outdoors since it is still bright outside. Daylight savings time is good for people who drive home from work since there are less chances of accidents since drivers can see better because of the lights. Crime is also prevented this time since it is committed in dark areas.
Not everyone is convinced of the benefits of daylight savings time. People want to end the practice of turning the clock back or forward twice a year. Since they perceive very few benefits of daylight savings time, they refuse to adjust their clocks twice a year. There are also those who think that daylight savings time disrupts their sleeping pattern since they have to adjust their clock setting backward of forward. And for those who forget to change their clocks, they are either later for work ro too early for it.
