is daylight saving necessary at all?


assistant
Absolutely no! Daylight Savings originated around WWI in an effort to conserve fuel and electricity. US enacted the act to preserve Daylight saving time in 1918 and established standard time zone across the States. However, with modern power grids and diverse night life, Daylight Savings is seemingly not relevant today. A lot of people complain about the inconvenience in turning the clock back and forth twice a year. The rate of being late for schedules or air flights on the day of daylight saving starts or ends every year is much higher than any other day in a year. In fact, even in the US, Arizona and Hawaii do not recognize daylight saving time. So do a lot of other countries like China and Japan. For European countries, the daylight saving switch date differs from one to another. All the chaos of daylight saving cause more trouble in schedule across-region appointments and meetings than any benefits of it if we can think of any.
