In 2005 the UN General Assembly designated 27 January as the International Day of Commemoration to honour the victims of the Holocaust.
The date is the anniversary of the liberation of the Auschwitz-Birkenau concentration camp in Poland in 1945.
When designating the day, the UN urged its member states to mark the day every year, and to develop educational programmes so that the young generations can learn about the tragedy of Holocaust in order to prevent genocide from occurring again.
