This section provides useful information regarding the national days of remembrance and public holidays observed in Germany. It is important to note that Germany's constitution, the Basic Law, confers no express legislative powers on the Federation to regulate public holidays. The federal states are responsible for observing the individual holidays. An exception to this rule – due to its status as a state symbol – is the national holiday: The Day of German Unity on 3 October is by its very nature regulated by federal law under the Treaty between the Federal Republic of Germany and the German Democratic Republic on the Establishment of German Unity (Unification Treaty).
