It's possible I did not explain myself. I often fall into that trap.
I do believe that dates MAY be significant, but am not 100% sure. It depends on if you want to get into intricacies and if you want to believe that terrorists care what the date is on "our" calendar. 9/11 does look significant because it is our emergency code, but was it really and are we in the west focusing on it incorrectly? I don't think we can say 'for sure' that the attack was chosen for that date or if it was just the prime opportunity to hit us (when Allah was willing).
I focused on 1, 19, and 40 because they are directly from the Qur'an.
1, is obvious... in relations to the "One God," "the one."
19, 19 is the mystery number that I am not sure why no one focuses on more. We saw 19 hijackers on 9/11 (19 embedded in the number) and in many instances after that. There are NUMEROUS references to 19 in the Qur'an and it is believed to be part of a 'miracle code.' One interesting instance; The word 'One', in Arabic "Wahid," in reference to God, occurs 19 times
throughout the Quran.
Here is some info on the number 19, some interesting stuff if you are interested.

40, well, 40 is a significant number to all Abrahamic religions in some way. It goes back to the flood I believe.
Now that you mention 19, I see it everywhere.
A telephone call prompted Philadelphia International Airport officials to evacuate 19 passengers from an American Airlines flight preparing to leave for Boston this morning.
American Airlines Flight 4543 was preparing to depart from Gate A2 about 6:30 a.m., airport spokesman Mark Pesce said.
Shortly after 6 a.m., officials received a phone call about "an item" on the plane, Pesce said.
He said the passengers were taken off the plane and rescreened. The plane was towed to a remote area of the airport where it was searched. Nothing was found, he said.
Pesce said he couldn't comment on the possible nature of the item or possible origin of the call.
