On Dates in the Bible

Hey Will,

Why is the exact and day, month and year date of the creation of the world, Jesus' birth, crucifixion, death and resurrection not recorded in the Bible when so many other events in history have dates recorded- like Julius Caesar's assassination on the Ides of March? How and why will people believe and what will make them believe in the Biblical events even when the exact dates are not recorded? Are there other events in history that do not have an exact or vague recording?"

Why would it be desirable to have the exact dates? Would that make them more believable? We know pretty precisely when they were, and even when the NT documents were written. I am just not sure how more precision in dating would increase their believability. You can think of examples of when something is precisely dated but is fabricated (read the preface or intro to the novel, The Name of the Rose for a brilliant example of creating an illusion through historical "precision"), or of countless historical events that are dated after the fact but not during.
