I don't claim 100% certainty that my timeline of end times Bible prophecy fulfillment is on target. But you also shouldn't 100% rule out the possibility that someone can calculate the time of such events based on the mistranslation you know so well of Matthew 24:36 - "No one knows the hour or the day." The original Greek verb, "oiden" translates literally as "no one has known" or "no one knows yet" and only rules out people knowing when the words were spoken in the year 33 A.D. No one knew how to build a jet engine then either.
