The timeline for Season 6 of Miraculous is a real mess. Thomas Astruc explained it this way: the season is like a puzzle where each piece represents an episode. No matter what order you put the pieces together in, the final picture will remain the same.

Despite that, we’re going to try to piece together the timeline. I should point out, though, that the chronological order is NOT the correct viewing order for the series (I might write a post about that order at the end of the season if I have the courage).

The episodes in italics are those that haven’t aired yet.
