actually, the Wiki took into canon the Google+ campaign, which this timeline didn't.
One of their post says that crime rate in NY is lowering alluding to Daredevil, and for that to be true, Darevil must be around for some time and also before the Hell's Kitchen explosion, as the post was released in January I don't remmeber 2015, this places Daredevil season 1 between January to February, and so Jessica goes to March trough April and so forth and on.
So tecnically both this and the wiki are right, this timeline just decided to build it around dates in the Series, while the wiki was altered by the posts.
