Daylight saving time was first introduced during World War I by the German Empire in the years 1916 to 1918.
After the end of the war and the proclamation of the Weimar Republic in November 1918, daylight saving time ceased to be observed.
In 1996, daylight saving time was harmonised throughout the European Union by Directive 2000/84/EC, which moved the end of DST to the last Sunday in October.
