AD and BC Calendar Dating System

What is Dating System ?

The date is a unique Identification of any day or Event in the Past, or in the future. It is represented in the form of day, Month, and Year. It started with the Birth of Jesus Christ, the Founder of Christianity.

To Point an Event in History We Need a System of Dating. AD and BC Dating System helps us to do So. BC is the acronym of Before Christ. That means any date Before the Birth of Jesus Christ is Known as Before Christ and it is Denoted by BC. Similarly, any Date which is after the birth of Jesus is denoted as AD or Anno Domini. It is a Latin word that means In the Year of Lord Jesus. Hence, dating starts with the birth of Jesus Christ and counted Forward from 0 AD as 1 AD, 2 AD, 3 AD, and so on.

The Date Before the Birth of Jesus Christ is counted backward as 63 BC, 62 BC, 61 BC, and So on. For Example, if Someone asks you, "which Year came First 12BC or 18 BC ?" You may go with 12 BC but, the right answer would be 18BC because BC represents Before the Birth of Christ so, it has been counted in the Backward Direction and 18BC comes first then 12BC appeared in the Chronology.
