Percy Jackson and the Olympians/Heroes of Olympus series timeline

[greenconverses]

This is something I've been messing around with since Son of Neptune came out and there was a lot of head scratching done about Riordan's numbers game regarding when Jason and Percy went missing. So I decided to be a nerd a finish it up this week. I posted a rough draft on tumblr last night and went back to finalize it up and reformat it before posting it here.

I tried to be as accurate as possible, but there's probably a 1-2 year error on anything that isn't specifically stated with a year date in canon which wasn't much, to tell you the truth. I based most of the PJO events on Percy's birthday since it was one of the few dates we actually had in canon and to get his year date, I subtracted 16 from the year The Last Olympian was published (2009) to get his birthdate at August 18, 1993. Everything else was based largely on what was found in canon, but some of that is still contradictory and up to interpretation.

Feel free to ask questions about how I decided on certain dates or argue with me about stuff on the timeline. I love to nerd out about this stuff. I'll probably update the timeline as more information comes out.

I wish I had words to explain how much it bugs me that I don't know Annabeth's Official Birthday.

It's a lot.

[greenconverses.livejournal.com]

SOMEDAY WE WILL LEARN IT.

[artemisrae.livejournal.com]

Purely out of curiosity, where did you get February for her?

[greenconverses.livejournal.com]

The UK PJO site has her age as 13 and a half when Percy is 13, so I went with the literal six months. She could probably be January or early March too.

[mediate89.livejournal.com]

When I played Annabeth on the rpg I had her birthday as February...12 I think? I don't think I knew that she was six months older than Percy at the time, I just picked a random month and day. Works for me. I'm betting we might find out in the new series though.

[artemisrae.livejournal.com]

Cool. My official head canon always had Athena giving her to Dr. Chase once he finished school, which means I had guessed either January or June and went with January. I'm somewhat pleased that I might actually be in range.

Dates

[heyitstempest]

I think in house of hades it was revealed as July 12th? (Spoiler alert) as they were in Tartarus Annabeth said something about how she didn't want to die (I think I can't remember at all) and she mentioned her age and said she was assuming her birthday, July 12th, hadn't already passed.

[belongtotheday.livejournal.com]

Best post ever? Yes? Yes. Will revisit frequently for reference I'm sure :)

[greenconverses.livejournal.com]

This reminds me that I should've included a, "This is how old each character are compared to the other!" section since that's something I frequently have to remind myself.

[oneoffour111.livejournal.com]

I feel like this will be very useful in the future. Nice!

[greenconverses.livejournal.com]

I hope it is useful for you or anyone else. I just wanted to clear up the six/eight months mess and it lend to this thing.

[saturninepen.livejournal.com]

You finished it! I was just thinking about this the other day, actually, and now that it's here, I just want to marry this post.

[greenconverses.livejournal.com]

I think I forgot about it for a while? You know how I am with projects and such. :P

It was really easy once I got started and I didn't want to sleep last night, so...

[poptartmuse.livejournal.com]

dying, this is incredible. small note, under 2010s, you've got June 19/20: Percy arrives at Camp Half-Blood when it should be Camp Jupiter.

love this so much!!! great work!

[greenconverses.livejournal.com]

Thanks for catching that! I was staring at that date earlier and I couldn't tell what I thought was wrong with it.

[allisnow.livejournal.com]

This is very cool :)

[princesethking.livejournal.com]

Still don't agree with the Civil War for the reason the camps got split... /Grumble grumble

[lovelysolitude.livejournal.com]

OCD at it's finest, this is~

[heyitstempest]

By the way- I think you got Bianca/Nico and Hazel mixed up. In Son of Neptune I think it was, a goddess asked Hazel about when her death was, and Hazel corrected her by saying "1942" so that's when hazel died, at 12 years old, so she was born in 1930. She also says that nico was born only a few years after her (she said this in SoN around the time when Percy 'met' Nico) so nico was born in about 1933. Also Bianca is older than Nico by idk how many years, it's probably mentioned in TTC.

precisions

[vivanecarstairs]

I think Nico would have been born around 1932 based on the fact that he was 10 in december 2007 and that was about a year after he had been taken out of the casino. Also, he and Bianca were put in the casino probably around the time of the discovery of the Great Prophecy and a while after their mother died (they spent time in a Washington bording school). Before she died, in the beginning of WW2, they moved to Washington with their mother.
