it cant be Wookie man, cause that was way earlier and she seemed to be just pregant and not full-on pregant

Am I the only one who noticed, that they got all confused with the Years? In the first episode "Summer" a banner in the town said : Welcome to 2016 but when Emily picked up the flyer for the whale museum it said 2016 as well and so did the wedding date of Lorelai and Luke 5th November 2016. That doesnt work ?!
