Harry Potter világában mindenki a születésnapján kapja meg a felvételi levelet?

Harry nem a születésnapján kapta meg az első levelét, gondolj bele, Vernon bácsi kidobta, több nappal a születésnapja előtt. Tucatjával jöttek a levelek, napokig. Végül Hagrid a születésnapján adta oda neki, igen, de az csupán véletlen.

"Since Harry received his first letter about a week before his birthday and most of the subsequent ones between then and his birthday, it is a wide misconception that students receive the letter around their 11th birthdays. he happened to receive his final letter that he actually read through Hagrid on his birthday.

At the very least students who have August birthdays would need to receive their letters prior to their birthdays as the cut off date for confirming their places is July the 31st and they would also need time to get supplies.

It was confirmed on Pottermore that Minerva McGonagall received her letter exactly on her birthday, meaning it does sometimes happen, though not always."
