We all know that Hogwarts begins on the 1st September.
Is there a reason given that it's always the same date, leading to various days of the week? In 1991 and 1996 it was a Sunday!
I am a teacher in the UK and we tend to start around the 4th but it could be anything from 2nd to 6th.
Also, I know JK Rowling admits to being poor with maths, but I feel this is a deliberate choice and not a mistake. Is magic supposed to be involved?
