Here’s a few different takes on the calculation of the seventy weeks. All of these scholars apply it to the Christ. The phrase “to bring in everlasting righteousness” (Dan. 9:24 ESV) can only refer to the Christ. Applying this to Antiochus IV Epiphanes is ridiculous:
Those who take the messianic view of this prophecy and who understand the time reckoning literally do not all hold to the same method of calculation. Gleason Archer and Stephen Miller believe that the sixty-nine sevens extended from the decree of Artaxerxes with Ezra about 457 BC to the commencement of Christ’s public ministry in 26/27 CE, based on solar year calculations (Gleason Archer, “Daniel,” in The Expositor’s Bible Commentary, vol. 7 [Grand Rapids: Zondervan, 1985], pp. 114-116; Stephen Miller, Daniel, New American Commentary [Nashville: Broadman & Holman, 1994], pp. 263-265). But Harold Hoehner and Paul Feinberg believe that the sixty-nine sevens extend from the decree of Artaxerxes with Nehemiah in 444 BC to the passion week of Christ in 33 CE, based on prophetic or lunar years of 360 days. With either view the effect is the same: the calculations are literally true of Christ (Hoehner, “Chronological Aspects of the Life of Christ; Part VI: Daniel’s Seventy Weeks and New Testament Chronology,” pp. 47-65; and Feinberg, “An Exegetical and Theological Study of Daniel 9:24-27,” pp. 189-220).
