No, you are getting completely wrong. That's not how prophecy works.
The correct way is to wait until Aug 21. Then, if something happened on the 20th, you look for an obscure biblical verse whose meaning you can distort and misconstrue so as to make it look as if it predicted that event on Aug 20. You then announce that as a biblical prophecy that has been fulfilled.
