First I just wanted to know how much time has passed between "Winter Is Coming" (Game of Thrones, S01E01) and "The Dragon and the Wolf" (Game of Thrones, S07E07), but I guess a more specific answer would be of more value to the community.
Even after having read all of the books, I just have lost the overview how much time has passed. E.g. Sam is riding slowly from Oldtown to Winterfell during the winter. Even that must have taken a year or so... Anyone who can help me.
