Yes actually. Well, 8 days from the end of this episode. I was just cleaning off my computer and found the timeline I put together back when Sophia was still missing.
Season 1
Episode 101 - Rick meets Morgan and his son and his son’s shovel.
Day 1 - Next day? They go out, check Rick’s house, go to police station, part ways. Rick runs out of gas, rides the horse into Atlanta, gets stuck in tank. (My numbering system starts here because it’s the earliest that can be counted accurately. He could have spent a night or a whole month at Morgan’s, no one knows, but days can be counted accurately from here on out)
Episode 102 - Rick is in the tank, meets the group, escapes Atlanta.
Episode 103 - they get back to campsite and he meets his wife.
Day 2- Daryl returns. They went back to town, found Daryl’s brother’s hand. Episode 104 - they got the bag of guns, met the Vatos and came back mid zombie attack.
Day 3- Episode 105 -They bury their dead, Jim starts to get sick. They talk about going to the CDC. Shane tells the group that they’ll leave first thing in the morning.
Day 4 - …although Atlanta is within sight of the camp and they don’t reach the CDC until dark. How did it take them that long to get there? Who knows.They spend the night there.
Day 5- They discuss the countdown timer, break out of the CDC, it blows up.
Season 2
Day 7- Season 2 starts out with Rick talking into the radio to Morgan and he says they lost another one of their group the "day before last. They load up, hit the road and get stuck in traffic. Shortly after getting stuck in traffic, Sophia goes missing. They look but give up at dark.
Day 8- The next day they find the church, Carl is shot and Shane/Otis go to the school that night.
Day 9- Otis memorial in morning, Daryl searching for Sophia, Glen nearly getting done by a zombie in the well, ends up getting done by Maggie instead. Episode ends at night to the sounds of crickets and Rick’s wife peeing.
Day 10 - Episode 205 starts with Lori waking up as others plan the Sophia search. Daryl says he’s going to borrow a horse. Daryl falls down ravine a couple of times, gets shot by Andrea, everyone meets for dinner, Glenn goes to the barn to meet Maggie, finds zombies instead.
Day 11- episode 206. Not much happens. Glenn tells Dale about the barn, Dale talks to Hershel. Glen gets abortion pills, Lori takes them, barfs, episode ends with her and Rick having an evening talk about babies and Shane.
Day 12- 207 opens with Glenn interrupting breakfast to tell everyone about the barn. When they go look at it, Dale speaks up and says he talked to Hershel yesterday and that he thought they could survive one more night without knowing about the barn. Episode ends with Sohpia taking one in the head.
I’ve only skimmed the last two episodes, but it seems clear that they only span the rest of day 12 and part of 13 and the CDC blew up on day 5.
