There seems to be a math error in this:

Still, there is compelling data that suggests "Storm Front" takes place in 1999, putting Harry's birth in 1974:
 
IF 3 ASF is 2003 then 0 ASF would be 2000, and if Harry was 25 in March of 2000 then he would have been born in 1974.(remember his birthday is October 31)

Harry being born in '74 does not conflict with Copperfield because Copperfield's first big job in show business was starring in the musical "The Magic Man" which opened in Chicago in March of 1974

I agree with you here. I've tried to point out the same thing. FWIW, I'm still in the "Storm Front is in 2000" camp, which would have Harry being born in '74, as you've mentioned.

True, it could  have been the first week of March. Though that is still verging on month 5.

Can't argue there - time is tricky. I haven't read it yet, but I get the feeling that "February and/or March" may end up being the appropriate end-point for it. Hopefully, we'll have a better answer by the end of War Cry.

That said, I've found that quotes from dialogue make things tenuous to pin down - especially with the graphic novels. Take Ghoul Goblin for example. Jim refers to the events of Fool Moon as occurring "only weeks" prior in Issue #1, while in Issue #2, it's "several months" (this is also indicated in the synopsis text at the beginning of the issues/HC). I'm inclined to go with the one in the synopsis, as people's recollection of time is fallible (doubly so when you're dealing with a fictional character's recollection of time), whereas narrative text should theoretically be more reliable.

We don't know for a fact Harry was exactly 25 in Storm Front.  I can't imagine him being younger than 24, but yeah.  Not necessarily 25.

Fair point - I'd thought that we'd gotten some confirmation from Jim on that one, but you'd know much better than I would.  The rest of this isn't an argument against your logic (or anyone else's) per se - rather it's an attempt to finally get to the bottom of all this.    In all seriousness - please feel free to show I'm wrong on anything here.  I'd rather have the right answer than think I do and be wrong.

That being said, DM's election year mention always had me placing that in 2003, and working backward from there would put SF and FM in 2000 (regardless of Harry's age).

I'd set up my mini-timeline site to help myself (and others, if they'd like to reference it) for placing the stories - I've found it especially useful for placing adventures in the DFRPG, for example.  In digging through all of that, and using the comprehensive timeline from this thread coupled with my own notes, I've been using the following as a set of guide-posts (all month counts in ages rounded down):

• Harry is 19 when he leaves Ebeneezer (minimum age - 19y0mo)
• Harry wanders around for 9-20 months (minimum age - 19y9mo)
• Harry takes several jobs before joining Ragged Angel (minimum age - 20y0mo)
• Harry works for Ragged Angel for 3 years (minimum age - 23y0mo)
• Harry is in business for himself ~ 5 years by the time Death Masks happens (minimum age - 28y0mo)

Since Death Masks is in February (Harry would be ~28y3mo by the above math), and Storm Front is just shy of 3 years earlier (Harry is ~25y4mo), Harry is pretty much always 25 in my head during Storm Front.

Even if we compress the "Harry wanders" and "odd jobs" periods, the youngest Harry could start his own agency would be ~22 1/2 years old (19 when he left Ebeneezer, 3 years with Nick, plus time to move around).  That could make him 24 during Storm Front, but I think that's pushing it.  I completely agree that 23 is right out.

On the Knight Rider question, apparently there were episodes being aired in syndication all the way into the 90s: http://knightrideronline.com/forum/viewtopic.php?f=2&t=17719  Couple that with the fact that a twelve-almost-thirteen Harry born in 1974 would be preferring to watch an episode aired in 1987, and I don't know how much the Knight Rider piece of the debate holds up anymore (as much as I wanted it to... ).

Now for some more headache-inducing analysis of all of this.

If we assume that the youngest Harry could be is 24 in Storm Front, and the oldest he could be is 29 (just to have an upper bound on things - I don't think anyone thinks that Harry is 30 when Storm Front rolls around).  We'll narrow these ages in a second, but I think these boundaries are very reasonable.

The earliest logical date for Harry to be born is 10/31/1974 (due to the Copperfield dilemma), placing Storm Front between 1999 (age 24) and 2004 (age 29).

The latest logical time for Death Masks would be ~2004 (as the Shroud of Turin incident - a "few years" before - has a hard dated year of 1997).  That being said, Death Masks makes, by far, the most sense being placed in 2003 due to the mayoral election year.  Here, Harry would be between ages 27 and 32.  However, if we assume that Death Masks has a hard date of Feburary 2003 (1999 is too early, 2007 too late), and Harry born no earlier than October of 1974, the oldest he could be during DM is 28 (having turned 28 in October of 2002).  This doesn't leave a lot of wiggle room - if he's 27 or 28 in DM, that makes him 24 or 25 during Storm Front.

That having been said, we've been given that slew of time units I rattled off earlier in this post, which adds up to 28 years and change.  So for me, the logical conclusion is that Harry is 28 in DM (taking place in 2003), 25 in SF (taking place in 2000), and as a result, born in 1974.

I've convinced myself on this too many times - I guess the question is, have I convinced anyone else, and is anyone of a mind to dissuade me from some logical fallacy I might have overlooked here?

Another note on specifically on Ghoul Goblin, actually.  According to issue 2, it takes place between a few weeks and several months after Fool Moon.  I will be as non-spoliery as I can with the references here.

Issue 1: (Harry, thinking...) "Because I screwed up, a group of werewolves unleashed a bloodbath that claimed my best friend's partner. That was only weeks ago."
Isse 2: (Harry thinking again) "My mind took an involuntary leap back several months. Murphy had survived the MacFinn case, but many others weren't so lucky.*"

The nature of comics are going to cause some inconsistencies (there are a couple in Ghoul Goblin so far that jump off the page at me), but in terms of placement in the timeline, we already knew which novels it was between (http://www.jim-butcher.com/posts/2012/ghoul-goblin-1-preview)

Based on the "several months" comment from issue two (and the lead-in text before each issue, actually), and the fact that Harry is freezing in one of the scenes where he is, I'd place the story roughly in February following Fool Moon, maybe March... much later would start getting warmer where he's at, almost too warm for the scene and his reactions in issue 3 to play out the way that they do.

I haven't read the Bigfoot stories yet, so I don't know if that's before or after "B is for Bigfoot" in the timeline, but I'm very confident we can add this to the timeline as:

1 ASF, February or March: Ghoul Goblin. Several months after Fool Moon, but early enough in the year for freezing temperatures in Missouri.

You know, with Priscellie's review and OK, of course.
