At 4 am Sunday, October 27, Bulgaria will turn the clocks back one hour to winter (astronomical) time until the last Sunday in March 2014.
As result the sunrise and sunsets will come earlier. Currently, the sun rises around 7:30-7:40 am and goes down around 6 pm. Starting Sunday the sunrise will be between 6:30-6:40 am and the sunset around 5 pm.
The daylight savings time was introduced in Bulgaria on April 1, 1979. It was introduced for the first time ever in 1908 in Great Britain to optimize the daylight hours.
Since 1981 European Community (EC) Directives have prescribed the start and end dates of summer time in member states. These are set as the last Sundays in March and October respectively.
The main idea behind this switch is to preserve energy by using natural light longer.
Yet, the implementation of Daylight Saving Time has been fraught with controversy ever since Benjamin Franklin first conceived of the idea.
Even today, regions and countries still change their approaches to Daylight Saving Time.
