There are some people who prefer daylight savings time for its own sake...but I am not one of those. I would like to keep standard time year round.
Perhaps a bit cynically, I believe the primary reason for daylight savings time is that businesses make more money, with one more hour of daylight for people to shop! However, there is a cost involved - you even read there are more auto accidents in the days immediately after the time changes.
However, the state of Arizona has standard time year-round (except for the Navajo Nation), and businesses seem to do okay there.
When Daylight Saving was first introduced in Australia it was explained that it was to create more leisure time for people to use after their working day finishes. From that point of view, it's worth doing.
We do it on a state-by-state basis so some states use it and others (those with large rural populations) do not. It makes it a little complicated for people doing business across state lines because they have to be aware of what time it is in each individual location. It's probably very complicated for residents living on either side of a state border, too.
It certainly makes a difference to what time I eat my evening meal. Leadfoot (that's Mrs Dodgy) is a gardener and likes to stay outdoors as long as there's enough daylight to kill a weed or trim a plant. From October to March that can be pretty late.
Trucker Lady once quoted an old Indian who said, "Only the government could believe that if you cut a piece off the end of a carpet and sew it on to the other end, you'd have a longer carpet."
Originally, Daylight savings time was created to allow rural communities to have more time, especially for the kids to have more time for chores when they come home from school. At the same time, there are those that want to keep it, so that when the little kids go to school that it's already light.. None of that makes a lot of sense... I remember when Pres. Bush wanted to have daylight savings all year long because people would have more light in the evenings and so use less electricity, saving oil. Of course, when it was shown that didn't make any difference, because people had to turn on the lights in the morning, he still felt it was a good idea.
All it does is create confusion for our bodies which are adjusted to their set schedule, so when all of a sudden we have to change by an hour... it's just pointless and I would abolish it myself if I could.
To give people more sunlight in the summer time. The clock then takes away that hour we add on November in Autumn cause no one wants to go outside anymore. When the extra hour is taken away it is called standard time. The clock will be moved an hour ahead in May which is spring.
My understanding is that daylight savings time was created so farmers had an extra hour during the fall so they could deliver their crops to market before it closed, I also heard that it had something do to with WW1, but not quite sure what.
