Question

when did when did dinoysius exigus invented the concept of AD and BC​

Answer 1

Answer:

There is no year zero in this scheme, thus the year AD 1 immediately follows the year 1 BC. This dating system was devised in 525 by Dionysius Exiguus of Scythia Minor, but was not widely used until the 9th century.

The B.C./A.D. system gained in popularity in the ninth century after Holy Roman Emperor Charlemagne adopted the system for dating acts of government throughout Europe. By the 15th century, all of Western Europe had adopted the B.C./A.D.
