exiguus

It was Dionysius Exiguus in the 6th century, who replaced the anno Diocletiani era with the Anno Domini era.

It was not exactly methodically chosen by Dionysius Exiguus in the 6th century.

The monk Dionysius Exiguus proposed anno Domini as a replacement for anno Diocletiani.

The current year numbering is because a monk called Dionysius Exiguus thought the existing system of numbering the years since Emperor Diocletian was stupid as Diocletian persecuted Christians.

If only Dionysius Exiguus had known about zero.

Well, epoch'd to Dionysius Exiguus's best guess as to the date of birth some five hundred and twenty odd years later...

But these are decimal years based on Dionysius Exiguus's miscalculations.

Bede used both these approaches on occasion but adopted a third method as his main approach to dating: the Anno Domini method invented by Dionysius Exiguus.

Wherever a modern zero would have been used, Bede and Dionysius Exiguus did use Latin number words, or the word nulla (meaning "nothing") alongside Roman numerals.[1][3][4] Zero was invented in India in the sixth century, and was either transferred or reinvented by the Arabs by about the eighth century.
