Did you know? AD or After Death actually means Anno Domini in Latin. This phrase means ‘in the year of our Lord’ and strangely starts on the year Jesus Christ was born instead of when he died. This dating system created by Dionysius Exiguus was not fully enforced until several centuries after Jesus’ death. It is believed that a mistake occurred revealing that Jesus’ actual birthdate is around 6-4 B.C. and not A.D. 1. Despite not knowing his true birth year, the birth, life, ministry, and resurrection of Jesus are still the events that shaped world history as we know it.
