"Stormy Weather" being in the Summer is most likely an actual continuity error accidentally caused by "Origins" not being released until the end of Season 1. I would personally disregard that "first day of Summer" line.

As to the rest of it, most of the so-called listed dates in the episodes are merely filler text to make things like calendars look more realistic. They should not be taken as any actual proof of continuity.
