There are many scriptural dates that are backed by history. When the scriptures tell us and or give us a sign or a forumla as to a certain event, then we know that the date is correct. Daniel tells us when the Messiah was to come, he doesn't give us an exact date, but he gives us the calculations.Now granted, one can manipulate the scriptures to arrive at a specific date, like the Witnesses do, a good example would be their Revelation book, and their Daniel and Jeremiah books, where prophecies have their fiulfillment in Watchtower history...no that is absurd.RR
