Holocaust Memorial Day or Holocaust Remembrance Day is an annual day designated by various countries to commemorate the millions of victims of Nazi Germany’s genocidal policies, especially the Holocaust, as well as to honour Holocaust survivors and their rescuers. The day on which the commemoration takes place may vary between countries, as may the name for the commemoration. The days are generally not declared public holidays.
The commemorations concentrate on contemporary efforts to battle hatred and antisemitism. 27 January marks the liberation of Auschwitz-Birkenau, the largest Nazi death camp.
