What is Daylight Savings Exactly...?


   DST used
   DST no longer used
   DST never used


It is that time of year again and as we move our clocks ahead one hour....we ask ourselves:  "WHY?"
Daylight Savings Time typically occurs at the start of spring and autumn, when we 'spring' forward and 'fall' back. According to my friends at Wikipedia, Modern DST was first proposed by George vernon Hudson in 1895...and the idea is simple, to advance the clocks an hour so afternoons have more daylight. 
The practice is controversial. Adding daylight to afternoons benefits retailing, sports, and other activities that exploit sunlight after working hours, but causes problems for farming, evening entertainment and other occupations tied to the sun. Traffic fatalities are reduced when there is extra afternoon daylight; its effect on health and crime is less clear. Although an early goal of DST was to reduce evening usage of incandescent lighting, formerly a primary use of electricity, modern heating and cooling usage patterns differ greatly, and research about how DST currently affects energy use is limited and often contradictory.
Looking at the map above, it's interesting to see how many locations around the globe practice it...
