The aim of the present study is to edit a manuscript of a Safavid calendar that was compiled by Mohammad Jafar Jonabadi, a member of the famous family of Jonabadi astronomers of the Safavid era. The manuscript is preserved in the National Library of Paris with the number Suppl. PERS. 376. The current manuscript is one of the most complete versions of calendars of the Safavid period. As far as we can tell, most of the few existing Safavid calendars are incomplete.
