Why do we still have daylight saving time?
Fewer than 40 percent of the world's countries observe daylight saving time, according to http://www.timeanddate.com. However, those that do are taking advantage of the natural daylight in the evenings. That's because the days start to get longer as Earth moves from the winter season to spring and summer, with the longest day of the year on the summer solstice. That's because during the summer, Earth, which revolves around its axis at an angle, is tilted directly toward the sun.
Regions farthest away from the equator and closer to the poles get the most benefit from the DST clock change, because there is a more dramatic change in sunlight throughout the seasons.
Research has also suggested that with more daylight in the evenings, there are fewer traffic accidents, as there are fewer cars on the road when it's dark outside. More daylight also could mean more outdoor exercise (or exercise at all) for full-time workers.
