The Friendship is Magic timeline going on episode release.

I'm sure by now people have already established the time line and chronology, but there's a lot of confusion over how many years have passed on the show. The show suffers like all cartoons and shows which have an out of order timeline, and there's really nothing to indicate how many years have passed based on the season certain episodes take place in. Silly little me to make writing writing Nyx fics easier (Past Sins takes place after Winter Wrap Up, or so the first two chapters say) I went through episode lists and came up with a timeline by year going on the episodes release and its place in the season, I will offer logical explanations if it gets confusing.

S1 Ep 01: Friendship is Magic Pt 01 - S1 Ep 11: Winter Wrap Up = year 01

S1 Ep 12: Call of the Cutie - S1 Ep 13: Fall Weather Friends = year 02 (The episode following Ep 13 depicts a summer or spring setting.)

S1 Ep 14: Suited for Success - S2 Ep 04: Luna Eclipsed = Year 03 (Following episode depicts a different season instead of a fall or winter setting.)

S2 Ep 11: Hearths Warming Eve - S5 Ep 5: Tanks for the Memories = Year 04 (following episode depicts a different season.)

S5 Ep 6: Appleloosa's Most Wanted = S5 EP 20: Hearthbreakers. Year 05.

S5 Ep 21: Scare Master (bypassed half a year.)

S5 Ep22: What About Discord - Due to the season depicted, likely seventh year in the show, ending with Season six Episode twenty two: A Hearths Warming Tale, which would mark the end of seventh year of the in show universe.

This timeline only applies to the episodes in order of release, the episodes, however can be jumbled into a proper order which could then trim the series down to taking place of the course of four years give or take. I preffer the episode order being jumbled back into a cohesive timeline, instead of a mess like the one I just made. But still, this is the timeline by episode release, if the creators have a timeline of a similar sense than I implore them to release it.
