Did God tell Daniel that The Messiah would arrive 445 years after the command was issued to rebuild Jerusalem?

The next date of major importance is the 20th year of Artaxerxes (Longim), the year Nehemiah received permission to go and rebuild Jerusalem. (Ne 2:1, 5-8) The reasons for favoring the date of 455 B.C.E. for this year as against the popular date of 445 B.C.E. The events of this year that involve the rebuilding of Jerusalem and its walls mark the starting point of the prophecy concerning the “seventy weeks” at Daniel 9:24-27. The weeks there are clearly “weeks of years” (Da 9:24, RS, AT, Mo), totaling 490 years. the prophecy pointed to Jesus’ appearance as the Messiah in the year 29 C.E.; his death at “the half of the week” or in the middle of the last week of years, that is, in 33 C.E.; and the end of the period of God’s special favor to the Jews in 36 C.E. Thus, the 70 weeks of years closed with the conversion of Cornelius, 490 years from the year 455 B.C.E.—Ac 10:30-33, 44-48; 11:1.
