Actually I dont think that the Great Prophecy will happen on Percy's birthday because on July 1, Ephialites said that Geae wakes up in one month which would mean on August 1. So please correct me if i'm wrong, but thats 17 days before Percy's birthday. So i'm sure the Great Prophecy will proabably not come true on Percy's birthday but I could be wrong.
