The first comprehensive study on the history of calendar reform and calendrical astronomy in medieval Europe, this volume draws on a range of sources over a period of more than 1600 years, from the Julian calendar of 46/45 BC to the Gregorian calendar reform of 1582, to shed new light on the place of astronomy in medieval intellectual culture.
