Adrien Agreste’s birthday
Okay guys, here’s why I think Adrien’s birthday is October 20th:
First off, we already know that Adrien’s birthday was in the first half of the school year, and it was before February 14th. Because of how awkward Marinette is in that episode compared to others, and February 14th is the earliest date actually specified in the show.
That means that Adrien’s birthday has to be between September 5th and February 14th. Why? Because I based the year off of a 2017-2018 school year (I’ll explain why later) and the first day of school in France in 2017 is September 4th. Adrien missed the first day of school, and met Marinette on the 5th.
I based it off of a 2017-2018 school calendar because on Marinette’s (Adrien’s) schedule, January 1st is on a Monday:
Now I played around with a time and date calendar, and found January 1st was on a Monday in 2018.
We can ignore this, because it’s the second semester, so I went back one year to 2017.
Okay, so, in order to narrow it down, I knew that his birthday couldn’t have been in January or February, because nothing was marked specially in those months on his schedule. That’s definitely something Marinette would’ve marked, because she obviously knew his birthday (strangely enough, Chloe forgot it??)
I also knew that it wasn’t between the 21st of October and November 5th, because on the school calendar, that’s a vacation period:
It wasn’t going to be November or later, because it would’ve been snowing by then, or at least autumn-colored leaves. The leaves were green and the weather seemed nice (probably around the 60′s-70′s temperature wise considering Adrien wore that type of scarf)
That leaves me with pretty much October. Sure, it’s possible it was near the end of September, but you may also be wondering why I decided specifically on the 20th?
Well, since I had already gotten this far, I figured, what if Thomas Astruc low-key aired it on his birthday (or at least really close to it)? Because we all know him, dropping hints that were actually pretty obvious but we don’t really see them anyway. Hey, it was worth a shot, you never know?
Okay, this makes sense… beginning of the year, before a fall holiday…
I remembered from the episode, that it was a Friday, Marinette says so (I marked the time it should automatically start at 0:24):
So I went to go check out the Friday’s in October, and whataya know:
Now I know this isn’t official, but hey, there’s a really high chance? Either way I’m pretty sure Adrien’s birthday is somewhere between September and October.
