How Much Time Has Passed on Game of Thrones? A Reasonable Timeline, Explained

Thank the old gods and the new for Robb's wife, Talisa. In episode seven, "The Bear and the Maiden Fair," she reveals the War of the Five Kings has been going on for two years. Since the war officially begins at the end of season one, the show appears to be covering roughly a year per season at this point. It's also worth noting that early in season three, Gilly gives birth to baby Sam at Craster's Keep. Meanwhile, Sansa reveals to Tyrion that she's 14 on their wedding night, and since their marriage occurs early in the season, she's likely 15 by the end of season three.
