Anno domini system of dating
In spite of these deficiencies, the dating system devised by Exiguus is now too deeply ensconced in the Western world to easily change.
At its core, that date—any date really—is just a code.
Some interesting events at that time were: 1 BCE: Some historians have concluded from their analysis of Josephus' writings that Herod the Great died in 1 BCE.

“In the Middle Ages and Antiquity, there were multiple eras jostling for recognition.”The key wasn't what Year One was, as much as getting everyone on the same page. “But because they were so powerful and influential, people picked up their calendar and dating system because it was convenient.”While these were the dominant systems, there was a hodge-podge of various cultures with different Year Ones. “One, they use the same year, so it's the same system.
(Let's not even discuss Year Zero, seeing as this jockeying for Year One position occurred before the concept of zero had even been invented.)
