Errors
During the initial years of the show, the year set was never formally mentioned, however, as the show progressed, time frames began to be mentioned in the show, leading to continuity errors throughout the series, such as:
 * Callie places Izzie on "George-watch 2007" in Season 3's Great Expectations, while Izzie claims it is 2009 in Season 5's Now or Never.
 * In "Let It Be" Miranda announces that she is pregnant, and nine episodes later, she has the baby. So, at least six months must have passed for Miranda to carry the baby to term, or she was already heavily pregnant when the show started (yet she only told others about the pregnancy in season 2)
 * In Season 6's "Goodbye", Lexie tells Mark it is her first day as a resident.
