A comprehensive review of the information on Georgian and Alouan (con­cerning the Caucasian Albania) calendars preserved in Anania Shirakouni's works and reached to our days was done. It was shown that in 561 The Alex­and­rian Council of 36 calendarists created similar (Egyptian-type) calendars for na­tions not participating the Council. This included the calendars created for Ar­me­nians, Georgians and Alouans, which, however, were not accepted in Ar­me­nia, Georgia and Caucasian Albania. 781 Completing its separation from the Ar­me­nian Church, the Georgian Church has put into practice the calendar created for it by the Alexandrian Council 220 years ago and started a new aera (the aera of Gergian Khronicon). And the Church from Caucasian Albania, always re­main­ing in the diocesan system of the Armenian Church, has never used the calendar created for it and has not had an independent area. 

The examination of the names of the months also showed that 83% of the Geor­gian names of the months and 67% of the names of the Albanian months are direct borrowings from the corresponding Armenian names or have a seman­tic similarity with them.
