Trying my hand at a little personal fan fiction with Post Season 8 stuff. It kind of requires a better bead on the timeline than the continuity errors - or at least I do. Here is what I have put together based on character ages and the two initial events that must have hard fixed dates:  Dexter being "3" in 1973 and Dexter being 20 when Harry dies.

Harry died in 1993, Season 1 takes place 10 years after Harry died – 2003. Astor is 9 in 2003. She is 12 in Season 5. So, Seasons 1-5 take place between 2003 and April, 2005. Harrison turns 1 in April, at the end of Season 5, and is 3 in the opening of Season 6. So, that makes Season 6 take place in 2007, after April. He is 4 when Hannah takes him to Argentina and Dexter fakes his own death, so all of Seasons 7 and 8 take place within 23 months or less of Season 6. And they can't go past the last fall available in that range: Dexter is living in Oregon by fall of 2008.
