Calendar Polemics in Medieval Judaism and Islam (9th-11th Centuries)

Workshop organized by Prof. Dr. Ronny Vollandt (LMU) and Prof. Sacha Stern, Ph.D. (UCL).

09.09.2019 – 10.09.2019

Calendars were a constitutive part of medieval culture, structuring social and economic life and providing a focus for communal and religious identities. How to reckon the calendar was at the heart of considerable polemics and controversies. In the Islamicate world, disagreements broke out between various groups within Judaism and Islam whether the calendar should be determined by the observation of natural phenomena or by calculation. This workshop examines the different approaches to fixing the calendar and considers the broader context, implications and textual practices of calendar polemics in the Islamicate world.

Participants among others: Gregor Schwarb (SOAS, London), Johannes Thomann (Universität Zürich), Nadia Vidro (UCL).
