how long was max in a coma stranger things

Max is in a coma for about eight days in Stranger Things season 4’s timeline, and then remains comatose for roughly a year and a half by the time season 5 begins.

In‑show timeline (season 4)

Within Stranger Things season 4, Max is attacked by Vecna on March 27, 1986, briefly dies, and is then revived by Eleven, but she does not regain consciousness and is left in a coma at the end of the season.

The season 4 story covers only several days, so from Max’s injury to the finale hospital scene, she has been in a coma for roughly a week (around eight days in-universe) when the season ends.

Time jump to season 5

Season 5 is set about 18 months after the events of season 4, and early information and coverage confirm that Max is still comatose at the start of season 5.

That means in the larger series timeline, Max has been in a coma for around a year and a half by the time the story picks up again, even though only days pass onscreen between her injury and the season 4 finale.

How long overall?

• In season 4 itself: about a week to a little over a week (the end‑of‑season hospital scenes).

• By the start of season 5: approximately 18 months in a coma in the broader Stranger Things timeline.

TL;DR: In Stranger Things season 4, Max is in a coma for about a week on- screen, but canon updates show she remains comatose for roughly 18 months by the time season 5 begins.
