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 Daylight Saving Time 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. With this economical and environmental savings, why switch back and forth?
The answer, NO REASON AT ALL! Think about it, would you rather have daylight after work, or not?
