Although I do not personally share that viewpoint, there IS some substantive evidence supporting the assertion that has been made by some in the fandom that Henry and his mother share a birthdate, so I don't think it's as clear-cut as you are trying to make it out to be regarding the placement of "The Jolly Roger" (3x17) in relation to this question.

What does seem clear, though, at least when all of the in-show evidence is parsed, is that Adam and Eddy's statement about Season 4 beginning in the "early part" of 2013 is inaccurate. However, even in taking all of that into account, all that we can truly conclusively say about the current timeline for Once Upon a Time is that, by the events of "Fall", the series has reached an internal chronological point of November of 2013.

Regarding the question of how much time passes between the events of "The Tower" and "There's No Place Like Home", I would put forth the argument that more time may in fact pass between those episodes than is currently believed, if only because of the way in which the episodes of Season 4 - which follow on directly from "There's No Place Like Home" do.

The reason I say this, BTW, is that we still don't know, conclusively, whether or not the second Curse slowed down time for the residents of Storybrooke, which makes trying to use Neal's date of conception to determine how much time the events of Season 3b actually covered more iffy than it might otherwise seem to be on the surface.
