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:

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:

• BC is placed after the number.

Example:

25 BC, 366 BC

• AD is placed before the number.

Example:

AD 454, AD 321.

• There is no ‘Year 0’ in history.
