The Stranger Things kids may have exposed Russian conspiracy plots in the third 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. The third season transpires in July 1985. In other words, the actors are aging along with their characters and the show, from the A/V club kiddos and their monster-hunting older siblings to their trustworthy parents like Joyce (played by Gen X icon Winona Ryder, currently 49 years old, born October 29, 1971) and Hopper (David Harbour, now 46 years old, born April 10, 1975).

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 the Stranger Things kids now, ahead of Season 4? Here's the breakdown.
