Among life’s greatest questions: Why are we here? Where did we come from? And for God’s sake, what season is it on The Walking Dead?

Yes: as we prepare to dive back into Season 7 of the zombie drama, we can’t help but fixate on the show’s most pervasive conundrum. It’s generally impossible to figure out what time of year it’s supposed to be on this show—even if you try to do it the logical way, by simply looking at what its characters are wearing. Clearly, people in the Walking Dead universe have very different internal body temperatures.

In a single hour-long episode, you’ll often see Michonne bare-armed and sweaty, while Negan cruises along zipped into a very thick-looking leather jacket. Negan himself looks equally comfortable whether he’s wearing his usual jacket and bandanna or just a white T-shirt. We’ve got Rick sweating through a button-down right next to Jesus in a floor-length leather jacket and a beanie.

This climatic confusion may have been plausible in Georgia—although, even there, it snows. But as the group pushes further north, the apparent lack of seasons on The Walking Dead becomes ever more puzzling. In fact, our best guess as to what the hell is happing actually may come not come from clothing at all, but from the Kingdom—specifically, its fresh fruit. Considering Ezekiel is able to offer Carol fresh apples and pomegranates, we’re guessing it’s some time between September and October.

Here, for your amusement on a Friday, is a detailed analysis of some of this season’s most perplexing costumes.
