The Stranger Things kids may have exposed Russian conspiracy plots in the recent installment of the series, Stranger Things 3, but one grand mystery persists: "How old is that curly-haired kid really?" 

First, some background: Stranger Things Season 1 took place in November 1983, in Hawkins, Indiana. Then, the Duffer brothers' follow-up Stranger Things 2 took the adventure to late October/early November in 1984, and the recent season takes place in in July 1985. In other words, the actors are aging along with their characters and the show. For casting director Carmen Cuba, her hunt for brilliant kid actors, which began around April 2015, meant sniffing out talent that could grow into the roles. 

"We needed every single actor to have a subtlety and an inner life that didn't necessarily need words to define them, and we held the kids and teens to the same standard," Cuba explained to Backstage. "We weren't thinking of them as kid or teen actors in the process -- the Duffer Brothers were really expecting them to be able to deliver a very rich human experience despite what age body they were in."

OK, so how old are they? Here's the breakdown.
