I'm in favor of moving Iron Fist Season 1 in early 2016 because of Chinese New Year in the first episode, and Iron Fist Season 2 in fall 2017 because the season's description suggests it takes place when Matt is still missing.
They were placed like this in our timeline because of dates seen on their phones or computers. But now that the official timeline has come out, there are prop dates that were ignored, so I don't mind ignoring certain ones in the Netflix shows.
I disagree with moving Jessica Jones Season 3 to later in spring 2018, because of Trish's co-host saying Mother's Day is in 6 months. I'd personally have it no later than late winter or early spring, so that it can be in a few months, while still being consistent with the mentions of spring fashion.
