oh my gosh i have a deep dive research i did to try and figure out their birthdays before i remembered brennan saying the time quangle fucks everything up, so i hence gave up but you can have what ive deduced so far (fair warning im posting this at 3am it has NOT been proofread)
In FHJY, episode 13, if you watch around or look in the transcript carefully, you'll realize this interaction with Fig happened during their time in Hell.
This throwaway line from Fig indicates that the “current” year is 1982. And taking the assumption that most 11th graders are 17 by the time the next school year starts, we can deduce that everyone was born roughly around 1965.
As all of you guys have probably picked up on, Lou refers to “Rock The Boat” as Fabian's 18th birthday, even though the entire storyline of him getting a bank account is supposed to be his 18th. I am hence taking that as the 18th birthday, and Rock The Boat as the 19th.
We can also narrow down Fabian's birthday month down to being May. Rock The Boat was (i think? its been a while) meant to be the last day of school. Unless your American state is weird, majority of schools end in May. Now. Im taking liberties here and saying if chappel roan can be in fantasy high, and a 21+ restriction on alcohol, so can memorial day. which falls on the last Monday of May.
Many states end school on the friday before memorial day weekend. And on 1983 (not 1982 the new year hasn't been celebrated at that point of jy, only moonar yulenear), memorial day was Monday, May 30.
Meaning Fabian's birthday is on May 27th, 1963, for him to be 19 years old during Rock The Boat.
(If you think about it, it can line up with his 18th bday too since the night yorb quest happened almost immediately into summer break of fhsy. His bank probably couldnt reach him when he turned 18 during the quest...)
ANYWAYS enough about Fabian next bad kids
During episode 7, as the downtime rolls are ongoing, a small scene of respite happens, when Brennan reveals this little tidbit:
Additionally, we get more confirmation from Murph a few seconds later that both Riz and Gorgug turn 17. (Zac has previously said that Gorgug was 17 during either a live show or sometime during FHSY. I am also fully ignoring this part.)
Murph said something about an ice cream party, when he said the turning 17 line, i can't be bothered to screenshot it but i promise on my entire soul that there's a line of it in the transcripts
Now, since Solace is a US-like country, I figured out that hey, cutoff dates exist. And boy I wish I didn't remember cutoff dates, because they were a nightmare for me to recalibrate and figure out correct years for everyone. But anyway, taking cutoff dates into account (around August-September), it just confirms that both green boys were born in 1965.
So, we have the year and the month of our beloved green boys.
Brennan said that they celebrated during the first week of October. and taking the widely accepted definition of “first week,” (meaning, the 1st can start on any day of the week--it starts on a Friday in 1965) means it puts our boys’ birthdates as either Oct 1st or 2nd in 1965 (coincidentally, 1982 also has the same dates as its first week).
We also know that even though they're both the first week, Gorgug and Riz do NOT have birthdays on the same day, since Gorgug clarifies that he doesn't want his own birthday party. Also (and you can read the episode transcript for this, there's not really a specific part) it seemed like the party DID happen on a school day, on Gorgug's birthday. Meaning, Gorgug’s birthday is most likely not on a weekend.
Since there's literally only 2 days available to choose from, and only 1 of them is a weekday, we can say that Gorgug was born on October 1st, 1965, and Riz was born October 2nd, 1965.
Now, moving onto Adaine. When Jawbone gave his gifts to Adaine when he adopted her in SY, there were 16 gifts there. Meaning that she’s already turned 16. Most spring breaks are held around mid to late March, meaning her birthday was before March, so we can comfortably abolish the beginning of JY as being canon. At least, I am. That cake was for Kristen and everyone else was celebrating her party.
Since there was no mention of Adaine's birthday during the Moonar Yulenear episodes, that gives her birthday the canonical range from January to mid-March, on the year 1966, to be 17 at the end of Junior Year.
I'm unsure how to narrow her down further, though. We could say that her birthday was during spring break, but then we probably would've seen mention of it somewhere during Sophomore year. If any of yall transcript lurkers want to feel free to check any mention for Adaine's birthday, be my guest, but in my searching I couldn't find much else.
For Fig, we’ve already had a canonical stated birthday being the 25th in fhfy. But fhjy doesn’t celebrate that, once again lumping her in with a summer birthday. I personally couldn’t find any other indicator in canon of her birthday otherwise, so she either is a May child, born 1966. or a Moonar Yulenear one. Her being born in May and being younger than all the bad kids is completely vibes based. Once again, feel free to see if you can't find any more bday info on her.
For Kristen, I do agree her birthday would be in the summer, Helio’s chosen and all. I personally believe she was born on the Summer Solstice, because isn’t that like the most fitting date? Also, to fit in with the whole cutoff dates, if we have Kristen turn 16 over the summer during the Night Yorb quest, she’d be in the same grade as the rest of the Bad Kids, meaning she was born on June 21st, 1966.
Adaine: January to mid-March who knows
Fig: it's either December 25th or literally any other date in the whole world. who knows but more intensified.
You can absolutely poke multiple holes in my assumptions and stuff, but canon is a weird timey-wimey ball in the land of fantasy high and so are ages
anyways thats its thank you for coming to my ted talk.
