In the eighth month of the second year of Darius, the word of the
LORD came to the prophet Zechariah son of Berekiah, the son of
Iddo... Zechariah 1:1 (NIV)
In the ancient world, time
was counted according to the reign of great kings. So the
calendar changed with the kingdoms.
Once the King of Kings was born into our world, all the
dates, forward and backward, were renumbered by that
event... and are never changed.
The incarnation of Jesus Christ marks the central event
of all human history!
Amen. Come, Lord Jesus.
