9/24/2013 is the last day of the countdown, which usually falls in line with some of the TV Shows premiering in Fall 2013. Calendar for Fall Shows
The link above will take you to a page where you can see all the shows that will be premiering on that day. Once show in Particular that peaks my interests is Marvel's Agents of S.H.I.E.L.D. I assume that most of you have heard about this show if not this is the wikipedia page. Now this is also in connection with the Paracelsus page where the page talks about daddy coming home. As most of you know in the Avengers movie Agent Phil Coulson died, but he is alive again in the show. So "Daddy" comes back home could be a jab at Phil Coulson is being resurrected back.
EDIT 1: I was on the Wikipedia page for the Avengers movie and the movie originally came out on April 11th 2012, in the movie the number of days passed were 3 days so the real world date would be April 14th 2012 (Which is also the day when the voice on Pronunciation Book says "Please help me escape from this place.") So my theory would be that Phil Coulson probably woke up in a weird place and started yelling out that he needs help.
