Rick Grimes was in a coma for roughly four to five weeks in The Walking Dead TV continuity, i.e., about one month.

Core timeline

  • Creator Robert Kirkman has clarified that Rick was unconscious for “between four and five weeks” after being shot, before waking up in the abandoned hospital.
  • This lines up with hints in the show, like Morgan mentioning the water shutting off about a month earlier and the general state of the hospital and surrounding bodies.

TV show vs. other sources

  • In the TV series, many fan breakdowns and interviews use the one‑month window as the accepted timeline for “how long was Rick in a coma.”
  • Some fan discussions and timeline analyses stretch this to “about two months,” but these are speculative; the on-record answer from the creators stays at roughly four to five weeks.

Why it feels longer

  • The world falls apart very fast in that first month of the outbreak, which makes Rick’s coma feel longer than it actually is.
  • The rapid collapse also fuels forum debates about Lori and Shane’s choices during Rick’s coma, which is why “how long was Rick in a coma” keeps trending in fan discussions.
