Daylight savings is actually an American (USA) invention....and it has some merit...me thinks.
Rare event, I know, but some merit it has.
It moves time to add one hour of extra morning and give one hour of extra afternoon. According to the clock that is. Think of it like this...Imagine if the standard working day started at 3am and ended at 11am. You would have a good 6 hours of daylight to do stuff like fishing, in winter, and even more daylight in summer !!
So the Yanks came up with this idea of moving the clock hands twice a year to give an extra hour of daylight in summer based on the working day. Guess that was easier than changing the working day and be done with it !! Easier to keep the standard working day at 9am to 5pm and just change the clock hands.
