Dark, Netflix's German-language sci-fi drama, has the well-earned reputation of being one of the most confusing shows on TV. Spanning multiple timelines and diving into the intricate connections between four families in a small German town, Dark was already somewhat difficult to follow before the third and final season introduced multiple universes and split realities. That's why we put together this timeline of everything that's happened on Dark in every world, reality, and time. 

But before you get to the timeline itself, let us explain some of the methodology that went into creating it so it's easier to understand and use.

[Warning: The following contains spoilers for Dark Season 3. Read at your own risk!]

When Eva uses the loophole to split reality during the 2020 apocalypse, she creates two realities. However, these two realities are inextricably intertwined and as a result are riddled with paradoxes (e.g. no one saving Jonas from the apocalypse allows for Adam to exist, but Adam kills the Martha who did save Jonas, even though he shouldn't exist because she saved him). To make things as simple as anything with this show can be, we created a labeling system for each reality (outlined in the key below below). It isn't a perfect system, since these realities overlap and exist simultaneously, but it can help illuminate when the realities most divide and how they coincide. For simplicity's sake, in Adam's world the default Reality is 1A and in Eva's world the default reality is 1B, even though some of the events exist across realities. When there are direct paradoxical moments -- such as Martha and Jonas' sons meddling in the reality where Adam exists and therefore the sons shouldn't -- we listed both realities that intersect. Additionally, since Martha and Jonas' son was never named, we refer to him as the Son(s) throughout.

Is it dispiriting knowing that 99.9 percent of the events detailed in this timeline wound up being wiped from existence when Jonas and Martha traveled into the origin world and saved Tannhaus' family, thus resulting in Eva and Adam's worlds never existing to begin with? Slightly! But understanding the complex, interwoven series of choices that led them to finally be able to break the cycle is enlightening and makes you appreciate just how expertly this show juggled its complex narratives across worlds, realities, and time. Read on for all the events in Dark in chronological order.
