Found this online and thought it was a handy reference tool. Thought I would include it here if you want to use it.

Dresden Files Series Chronology

• 0 ASF, March: Storm Front. Harry is 25, according to Jim, and he’s been wizarding professionally for two years. We can reasonably place the year 0 in the timeline within a year or two of 2000. I went with 2000, for the dates used in my character’s backstory.
• 0 ASF, September (full moon): Harry travels to Minnesota. Someone saw something in a lake.
• 0 ASF, October (full moon): Fool Moon. Billy and Georgia are in college, probably freshman or sophomores, and definitely not yet 21 (legal age to rent a van in Chicago). [FM 41, 258]
• 0 ASF, November: Ghoul, Goblin graphic novel. A small town family is tormented by creatures of the Nevernever.
• 1 ASF: Harry sets up an arrangement with the Cobbs at Shoegasm, establishing their livelihood in exchange for a cease in their shrinking inventory. (Seven years before It’s My Birthday Too)
• 1 ASF: Thomas’ last job for the Oblivion War, until Backup. (Nearly 8 years before Backup, which takes place in March of 9 ASF)
• 1 ASF: B is for Bigfoot short story. Irwin is 8 or 9.
• 1 ASF, October: Grave Peril. Probably early October, so that there could be a few weeks between Susan’s departure and the birthday card she sends Harry on Halloween.
  Harry Carpenter is born and instantly doomed to get beaten up every day of his life. Harry meets Father Forthill sometime during the previous year, between Ghoul, Goblin in November of 0 ASF and Grave Peril.
• 2 ASF, January: Harry goes to a football game with the Alphas, and does not get out again until…
• 2 ASF, June (Midsummer): Summer Knight.
• June 16 — The Reds attack Archangel. Senior Council member Simon Pietrovitch (Justin’s old master and the Council’s vampire expert) is killed, among many others.
• June 17 — Murphy’s first husband, Gregory Taggart, dies of cancer at age 43.
• June 18 — A rain of toads, Harry makes his deal with Mab, the Council meeting is held, and Elaine returns.
• 3 ASF, late February: Death Masks. Susan has been gone about a year and a half. “A few years” after 1997, when the Shroud was nearly destroyed in a mysterious fire. [DM 28] Also, this is a mayoral election year, so we can assume with confidence that this book takes place in 2003.
• 3 ASF, late November: Assuming a nine-month pregnancy, Maggie is born.
• 3/4 ASF (between DM and BR): Vignette, short story.
• 4 ASF, summer: Mold demons devour the Beetle’s interior. They were “a present from the guest villain a few months ago.” Also, Harry travels to “exotic Oklahoma” and runs down a rogue storm sylph as a favor to the Summer Lady.
• 4 ASF: Molly manifests her magic.
• 4 ASF, late autumn: Blood Rites. We now know this takes place a year after DM, as after Inari’s failed attempt to seduce Harry, he tells Thomas that it had been over a year since he had been with Susan [BR 161]. We also know it takes place slightly less than two years before PG. We know that Lisa Murphy (Karrin’s youngest sister) is one month shy of 21, and that her fiancee Rick/Rich is nearly twice her age.
• Late 4 ASF/Early 5 ASF: Murphy begins teaching Harry to stick fight.
  From Heorot: “I don’t think Caine knew much about quarterstaff fighting. Murphy had been teaching it to me, however, for almost four years.”
• 5 ASF, October (Halloween): Dead Beat. Georgia is now in Grad School, which makes sense now that we know she was in college in FM. We’re not sure when they started grad school, but we do know that she and the rest of the Alphas are going to graduate in a year and a half. Ramirez is 20, according to Word of Jim.
