The Venerable Bede on reconciling ancient calendars and how he thought our 2 B.C. should really be 1 A.D.
Bede convincingly argued that our present 1 A.D. was incorrect by three years. He uncovers the fuzzy Church logic between 550 and 650 A.D. that made this error and subsequently has caused calendar headaches ever since.
The Venerable Bede was an eighth century monk who made a decisive effort to collect all the calendar systems he knew about, whether historic or contemporary to his time, and reconcile them into one dating system. This endeavour sounds easy by today’s standards, but was a massive undertaking during his time.
If any discussion revolves around the development of the yearly calendar system, his writings should be consulted. This study focuses on his works as it relates to Christ’s birth but other pertinent dates fall in as well.
How did he arrive at this conclusion? He did it through comparing different calendar systems and then developing two new time systems – one of them closely parallels the A.D. system in use today.
De Temporibus Liber and De Temporum Ratione.
Bede greatly pondered about time systems and wrote two books on the subject: De Temporibus Liber which is known in English as the The Book of Times and De Temporum Ratione, On the Reckoning of Time.
De Temporibus Liber, the first publication completed in 703, acknowledged the traditional Anno Mundi medieval dating system. The Anno Mundi system was based on totalling the ages of all the patriarchs listed genealogically in the Greek Bible and that was how the age of the world was arrived at. He did attempt to correct the imperfections of this system, finding that the Septuagint (Greek Bible) dated the ages of the patriarchs considerably longer than the Hebrew version. Bede preferred the Hebrew dates over the Septuagint, though the Greek was the standard for measuring time. To argue or change such an equation would be controversial. In order not to be in dispute with Church authority, he entered a Hebrew date with the Greek as an alternative. For example:
