Day one: Rick wakes up, gets found by Morgan and sleepsleeps in the house he has set up camp in.
Day two: Starts with Rick hitting the walker with the baseball bat. EndEnds with him sleeping with Lori at the camp in episode 3.
Day three: Starts with Rick and co. Headingheading to Atlanta to rescue Merle and the nag of guns. Ends with the camp being over runoverrun and Amy dying.
Day four: Starts with the group burying/burning bodies from the camp attack. Ends with the group sleeping in the CDC after their meal and Shane getting scratched by Lori
Day five: Near the beginning, Rick comments on ShanesShane's scratch mark he got offrom Lori, this. This must mean it happened the the following morning from arriving at the CDC, as Rick would've noticed the scratch earlier. Day ends with the CDC blowing up.
Day six: Not seen as Rick mentions in S2E1 "we lost somebody,day day before last".
Day seven: Starts with group heading theto that other camp. Ends with Shane shaving his head at the end of S2E3.
Day eight: Starts with Otis' funeral. You can tell because the Atlanta group show up and it makes sense in this situation to have the funeral the day after he died. Day ends with Lori finding out she's pregnant as Glen got the test the same day he got used as bait, and it's unlikely Lori would have waited another day to use the test.
Day 8: Rick actually comments in S2E5 on how many days it's been since Sophia went missing, but I can't remember what he says. This day ends with Daryl recovering after being shot.
Day 9: This day may not have been seen by us as well, as Daryl is now in his tent and may have needed more bed rest after his incident. Let's say it is the next day, -- it ends with Lori telling Rick her secrets.
Day 10: this is s2E7. Day starts with Glen telling of the walkers in the barn. Ends with Lori back at the farm after her incident and awaiting Ricks return from finding Herschel
Day 11: Starts with Rick and co. Returningreturning with Randall at the end of S2E9. There is a 10 day gap between ep 9 and 10 to allow Randall to heal after his wound.
Day 21: This day took place during S2E10 (which I actually have an original, signed script for :D)
Day 22: Starts with Daryl and Randall in talking in the shed. Ends with DalesDale's death.
Day 23: Starts with DalesDale's funeral. Ends during the farm attack, as it is morning when the group meet on the highway.
Day 24: ends with the view of the Prison.
What a busy month!
