According the Wikipedia Ben Franklin mentioned daylight saving as early as 1784. It was never implemented, however, until the First World War. The man credited with bringing the concept to fruition was New Zealand entymologist George Vernon Hudson who wrote a paper about it in 1895. When it finally came to pass, the practice was praised for its “benefits to retailing, sports and other activities that exploit sunlight after working hours.”
Though most of North America and Europe practice DST, there is a large swath of the world that used to do it but have abandoned it. And then there are many countries, in Africa and Asia that never adopted this practice that we take for granted in the first place.
Anecdotally, since DST always occurs on a Saturday night, it probably has an impact on church attendance on Sundays. (speculation) We had friends who were perpetually late to everything and sometimes arrived as much as forty minutes late to church. At a certain point of lateness, the husband would refuse to go in because of his embarrassment in this regard. One day, they decided to deal with it and determined to be early for a change. As the walked in, thinking it ten minutes before the service was supposed to start, they saw that the sermon was actually nearing its close. They had not realized Daylight Savings had reverted back.
In short, don't forget to pay attention to the times....
