This conference marks the culmination of a five-year research project funded by the European Research Council at the UCL Department of Hebrew and Jewish Studies, on  ‘Calendars in later Antiquity and the Middle Ages: standardization and fixation’. This project examines the history and evolution of calendars in late antique and medieval societies, with a special focus on Roman, Christian, Jewish, and Islamic calendars. The evolution of these calendars was closely related to politics, science, and religion, and contributed more widely to the standardization of culture in the ancient and medieval worlds. The conference presents the outcome of this research, together with contributions from international collaborators in the field.
