9th International Conference on the Science of Computus in Late Antiquity and the Middle Ages

Date: 19 June 2023 to 20 June 2023 at 09:00 to 16:30
Time: 09:00 - 16:30

A two-day hybrid conference organised by the School of Histories and Humanities. Since 2006, a biannual conference on the science of computus in Late Antiquity and the Middle Ages has been hosted in Ireland, first in Galway, now, in its 9th installment, in Dublin. Computus – the mathematics required to calculate the date of Easter, and related topics (incl. astronomical observations and calculations) – straddles the fields of mathematics and astronomy, biblical interpretation and cosmology, empirical astronomical observation, and the perennial quest to understand the concepts of time and time-reckoning. The core period covered by the Computus Conference stretches from the beginnings of Easter calculations in the third century to the introduction of Arabic and Greek science in the Latin West in the 12th century.
