What Is BC and AD?

When we talk about the Indian history timeline, we always use the terms BC and AD to refer to the period when a particular event occurred.

In the timeline, time is measured from the birth of Jesus Christ. Using this system, they describe any event they require.

Full form:

12 BC = 12 years before Christ. Years BC counts backwards.

It means that years with larger value BC happened before years with smaller value years BC.

Example:

Julius Caesar
Born: 100 BC
Died: 44BC

Years AD count forwards.

AD 45 = 45 years after the birth of Christ.
AD starts just after Jesus’s birth, not his death.

Important Rules:

   1. BC is placed after the number.

      Example:

       25 BC, 366 BC

   2. AD is placed before the number.

      Example:

        AD 454, AD 321.

   3. There is no ‘Year 0’ in history.
