Sabahattin Kalender (Taà Âlñca, Kosovo, 15 April 1919 â The Hague, 7 August 2012) was a Turkish composer. His works included the operas Nasrettin Hoca (opera) on the life of Nasreddin, Karagöz Operada and the oratorio Ateà  ve ðnanç ("Fire and Faith").
His father was a military officer who died in the First World War so Sabahattin was brought up in the Kalender Orphanage Istanbul from which he took his name.
