6 Months

 A bad day at work was redeemed by learning that the new, and last, series of Game of Thrones will be on in less than 6 months time.  At last, thank god.  I read a load of interesting fan theories on this last season - I won't list them here for spoilers sake, since I think some of them will probably come to pass, but inevitably I don't expect all the loose strands to be neatly resolved so I must manage expectations.  However knowing how Game of Thrones doesn't care for a happy ending, I expect the White Walkers to win the Great War.
