The Martyrs of Jasenovac were first memorialised in church calendars by the Serbian Orthodox Diocese in USA and Canada in 1980.

In the calendars printed by the then Diocese of America and Canada from New Gračanica near Chicago, the feast day of the Jasenovac Martyrs was also published.

Later, after the healing of that great church wound, grace by Patriarch Pavle, Metropolitan Irinej and other archbishops, the Holy Synod of Bishops of the Serbian Orthodox Church decided that their memory can be entered and celebrated in calendars printed by Serbian bishops abroad.

Since 2010, the feast day of the Holy New Martyrs of Jasenovac has been binding on the entire Serbian Orthodox Church.

On 16 April, 2010, the Holy Synod of Bishops of the Serbian Orthodox Church decided to canonise the Holy New Martyrs of Jasenovac, with their feast day on 31 August on the Julian Calendar

The New Martyrs of Jasenovac are mainly venerated and liturgically celebrated in the Jasenovac Monastery.^[3]
