A Handbook of Dates provides in clear, user-friendly form, tables that allow the calculation of the dates (and days) on which historical events have fallen or will fall, from AD 500 to 2100. It includes lists of Easter dates, saints' days, popes, rulers of England and the Roman calendar. In this updated and expanded edition, Michael Jones has edited or revised the explanatory sections and added new tables, for example on old and new style dates and Celtic Easter. A Handbook of Dates is an unrivaled reference tool for historians.
