Germany follows one time zone and that is CET which stands for Central European Time. During daylight savings time, Germany then follows the Central European Summer Time. In Germany, daylight saving time is enforced in March from the final Sunday to the final Sunday in October. The first time that daylight saving time was put into effect was during World War I.
It was introduced by the German Empire from 1916 to 1918. It was put into effect and then taken away many different times and it was not until 1996 that all of the European Union began using it.
