So I was reading a fanfiction and this crossed my mind.
Wouldn’t Percy have been 11 in Lightning thief due to the fact that it takes place at the end of the school year which probably places the start of his quest and time at camp in June. Later books state that his birthday is in August. And even if the first chapter states him as 12 it is immediately followed by the words until a few months ago I was a student at a boarding school(or something along those lines). He still would have been 11 for the course of the quest because he is back at camp for about a month before Luke betrays the camp. Which means it was July or early August considering that he o my had a week or two of training and then his 10 day quest.So he may not even be 12 by the end of the book.We know that sea of Monsters and Titans curse take place the same year one in summer and other in winter. Meaning depending on the month of summer he could very possibly be 12 in sea of monsters and 13 come titans curse.
This may be well known or at least something others have realized before. Or I could be terribly wrong. But just something that crossed my mind.
