On March 13, 2011, this Sunday, the current time was changed as daylight savings was implemented at 2 AM. Most of the people in America moved their clocks one hour forward to adjust the current time in light of DST.
Daylight Saving adjustment of current time is done in spring and it ends in fall. It is just like a race in which one wants to get ahead initially in start of the year and in fall wants to fall back by one hour to delay the winter. There is an old saying – spring ahead and fall back – which means moving one hour ahead in spring and going back by one hour in fall for the current time.
Some areas don’t change their current time for daylight savings ncluding Guam, Virgin Islands, Hawaii, Puerto Rico, American Samoa and most of the Arizona. They just maintain their standard time making no changes to the current time.
The DST period was extended by the energy policy act in 2005. According to new act, the time for daylight savings was increased in 2005. The purpose of the new act was to extend the period for at least two months but in fact it was extended for three weeks in spring and one week in fall. The logic behind this was objection from farmers and airlines as they faced problems due to the change. The airline objected as the other countries may no observe it thus creating problem in scheduling flights; the farmers argued that this change affected their livestock.
The idea of DST first came from Benjamin Franklin when he thought that changing the clocks in this way could help in extending the daylight hours. It made sense as there was no electricity at that time.
