The Ultimate Fanfic Writer's HIMYM timeline
The purpose of this timeline is as a resource for Fanfiction Writers, to help us cope with the contant flashbacks and flashforwards in the show, in order to get our continuity right (even if the writers themselves sometimes don't!)
Thanks are due to reese1410, roland44, waterwheel and da-phoenix13 for help with this.
A note on birthdays
Ted/Marshall/Lily are all born in 1978
Ted: 25 April (E1.20, 3.17)
Marshal/Lily: According to the Pilot Script, Marshall's birthday is 1 May (Ted is six days older).
Ted's birthday is the only one we know in canon, though Lily and Marshall were both born later in the year than he was (because Barney's the only other one who's 30 at the time of The Goat). And because Marshall says he's hittin' 30 pret-ty soon after Ted, Marshall's birthday.
We see Lily's 32nd birthday (E5.18) which was broadcast on 22 March 2010. However, we just have to assume that the episode is out of order and a product of Future-Ted's unreliable narration. Lily's birthday would more likely be sometime in the summer because of how the American school system works (the cutoff birthdate for most school systems is September 1; if Lily was born after that date, she'd be a year behind Marshall and Ted in school). It's likely that Lily is also a May baby.
Barney was most likely born in spring 1975 , sometime between July 20-23rd.
Note: E1.15 says he was 23 in 1998, E2.13 he says he is 31 in Jan 2007. It says here that the year of his birth is 1974 (E5.08) but that is a "fake" website. In E5.17 it clearly states he's 34, which confirms the 1975 birth year and that Barney was born sometime after March. In E5.19 Ted says that Barney was born seven years before the moon landing (1969) so he must have been born between July 20th and December 1975. Interestingly, in E6.08 it says that Barney was 6 years old on July 23rd 1981, so his birthday has got to be around then - and thus very close to Robin's.
Robin: July 23, 1980 (E5.03).
Note: In real life, Neil, Josh and Aly are older than their characters, while Jason and Cobie are younger. From the oldest to the youngest it goes: Neil (1973), Josh and Aly (1974), Jason (1980) and Cobie (1982)
The ultimate HIMYM Fanfiction Writers Timeline
1981
- Six year old Barney is kicked off the peewee basketball team (E6.02)
July 23 - Six year old Barney knocks down the Blue Whale with a triceratops bone in the Natural History Museum, accompanied by his "uncle" Jerome Whitaker (actually his father). This is the last time Barney saw his Uncle Jerry before 2010. (E6.08)
1982
- First Barney/James flashback (ice-cream) (E2.12)
1984
- Second Barney/James flashback (just one of those things) (E2.12)
1986
- Third Barney/James flashback (little racists) (E2.12)
1988
- Marshall reads "Life Among the Gorillas" and decides to save the environment. (E1.17) Note - he is 10 years old at this point, reinforcing his birth year as 1978.
1992/3
- Lily's incident with "Gasser". (E4.06)
- Marshall was chunky in 9th grade/when he was 15. (E1.17, E3.01)

- Robin has lived with her dad as a boy until this point (she was 14). (E4.06)
- Marshall gets his Fiero after several of his brothers' "tests". (E2.17)
1995
Summer - Ted loses his virginity to Molly McKenzie. (E2.12) He was 17 (1978 + 17 = 1995) and a junior in high school (E4.01). Summer, if only because Molly was going off to light firecrackers with her cousins in the woods, which seems like kind of a 4th-of-July thing to do. But it'd be any time after April 25 and before September.
4-Jul - Lily eats 27 hot dogs in 8 minutes (E4.15)
1996

Augt/Sep? - Robin loses her virginity to Brian (E2.12) Brian was most likely post-Simon (since Simon was her first real boyfriend) so this would be sometime after July.

"Late August" - Lily, Ted, and Marshall all meet each other as freshmen at Wesleyan University, Middletown, Connecticut. (3.05)
Fall - Lily and Marshall lose their virginity. (E2.12) They're freshmen, they met in the fall, and it's sometime before New Years Eve.

2000
Spring - Ted, Lily, Marshall graduate from Wesleyan and move to NYC. This is confirmed in E3.02 when Marshall says it has been eight years since he moved to New York (that was in 2008).
Note:-
- Ted would have to study a further year in grad school to get his B. Arch. (Probably Columbia)
- Lily might have also been studying for her M.Ed, but she could have gone straight into work in Elementary School with her B.Ed.

A note on birthdays
Ted/Marshall/Lily are all born in 1978
Ted: 25 April (E1.20, 3.17)
Marshal/Lily: According to the Pilot Script, Marshall's birthday is 1 May (Ted is six days older).
Ted's birthday is the only one we know in canon, though Lily and Marshall were both born later in the year than he was (because Barney's the only other one who's 30 at the time of The Goat). And because Marshall says he's hittin' 30 pret-ty soon after Ted, Marshall's birthday.

Lily's birthday would more likely be sometime in the summer because of how the American school system works (the cutoff birthdate for most school systems is September 1; if Lily was born after that date, she'd be a year behind Marshall and Ted in school). It's likely that Lily is also a May baby.
Barney was most likely born in spring 1975 , sometime between July 20-23rd.
Note: E1.15 says he was 23 in 1998, E2.13 he says he is 31 in Jan 2007. It says here that the year of his birth is 1974 (E5.08) but that is a "fake" website. In E5.17 it clearly states he's 34, which confirms the 1975 birth year and that Barney was born sometime after March. In E5.19 Ted says that Barney was born seven years before the moon landing (1969) so he must have been born between July 20th and December 1975. Interestingly, in E6.08 it says that Barney was 6 years old on July 23rd 1981, so his birthday has got to be around then - and thus very close to Robin's.
Robin: July 23, 1980 (E5.03).
Note: In real life, Neil, Josh and Aly are older than their characters, while Jason and Cobie are younger. From the oldest to the youngest it goes: Neil (1973), Josh and Aly (1974), Jason (1980) and Cobie (1982)
