How long does it take to watch Grey's Anatomy?

Grey's Anatomy is the longest-running American primetime medical drama and, at nearly 334 hours, one of the largest single-show commitments in television. It overtook ER's 331-episode record in 2019 and has kept going. Unlike most long-running dramas it has held a consistent 43-minute network hour throughout, which makes the arithmetic reliable in a way that HBO shows are not. Watching one episode every weeknight, starting today, you would finish in late 2028.
