Roman scholar and theologian Dionysius Exiguus (c. 465 A.D.-c. 530 A.D.) is best known for his creation of a calendar that led to the modern Gregorian calendar. From his calendar stem the designations “B.C.” and “A.D.” Dionysius championed the system that is still used to determine the date of Easter, and his many translations and writings have inf...
Dionysius Exiguus, the man, is something of a mystery to modern scholars; Writing in Anno Domini: The Origins of the Christian Era, Georges Declercq argued that “the epithet ‘exiguus’ was adopted by Dionysius himself as a sign of intellectual humility, not because he was small of stature (‘the Short’).” Beyond this issue of nomenclature, the detail...
During his career, Dionysius worked in several fields of study. He translated many of the decrees issued by the Council of Nicaea, which created the first standard Christian doctrine; decrees by the Council of Constantinople, which created the first major revision of that doctrine; decrees by the First Council of Ephesus, which declared Mary to be ...
According to the New Catholic Encyclopedia, “the entire work of Dionysius had but one purpose: the reconciliation of the Churches of the Orient and the West.” At the time of Dionysius, Christian doctrine was not yet standardized; the Christian world had divided into eastern and western branches due to disagreements on doctrinal matters. One of Dion...
In the course of determining the date of Easter, Dionysius also created the Christian Era calendar, commonly used today and recognizable by its B.C./A.D. (“Before Christ”/“Anno Domini”) designations.

Aug 22, 2017 · Even though Dionysius began the use of A.D. for the years after Jesus’ birth, he did not develop the use of B.C. for the years prior to Jesus—in fact, Dionysius rather wanted to exclude Roman figures like Julius Caesar and Nero from his timeline.
Finally in 525 AD under the direction of Pope John I, Dionysius Exiguus, a Scythian monk and scholar living in Rome, published new Easter tables based upon the Alexandrian computations, but converted from the Alexandrian to the Julian calendar.
The Julian calendar has two types of year: "normal" years of 365 days and "leap" years of 366 days. There is a simple cycle of three "normal" years followed by a leap year and this pattern repeats forever without exception. The Julian year is, therefore, on average 365.25 days long.
