Daniel 9:25 Know therefore and understand, that from the going forth of the commandment to restore and to build Jerusalem unto the Messiah the Prince shall be seven weeks, and threescore and two weeks: the street shall be built again, and the wall, even in troublous times. This decree was given to Nehemiah by Artaxerxes of Persia in 445 BC. Counting 483 biblical years [476 solar years] from the time king Artaxerxes of Persia issued a decree (445 BC.), comes out to A.D. 31. Jewish biblical year is 360 days. 69 x 7 = 483. 483 x 360 = 173,880 days. 173,880 days devided by 365.2422 = 476.06766 solar years. So, from the decree to Nehemiah on Nisan 2, 445 BC, counting 476.06766 years comes to Nisan 10, 31 AD, which was palm Sunday. That is when Jesus came to Jerusalem as Messiah, the king. [So it would come to Nisan 10, 31 AD. Since Jesus was born in 2 BC, this would make Him 33 years old, which matches His age at His death, and the date of palm Sunday.] Zechariah 9:9 Rejoice greatly, O daughter of Zion; shout, O daughter of Jerusalem: behold, thy King cometh unto thee: he is just, and having salvation; lowly, and riding upon an ass, and upon a colt the foal of an ass. http://144000.net/birth.htm Proof at this website Jesus was born in 2 BC.
