Millie Bobby Brown was around 18–19 years old during the filming and release window of Stranger Things season 5, depending on the exact production dates.

Age breakdown

• Millie Bobby Brown was born on 19 February 2004.

Why it’s an estimate

• Public biographical sources consistently confirm her 2004 birth year, which is the key fact used to approximate her age relative to the final seasons’ production period.
