Valky:
I think it's in another book not PS/SS, maybe POA. 
In any case I agree, I do recall that canon places Harrys age at 15
months, which would be approximately the end of October.

OTOH I think Hogwarts *was* closed/ish. The whole WW was celebrating
the downfall of Voldemort, I don't think Hogwarts would have excepted
itself from a WW party. Perhaps children were allowed to use the floo
to go home and whoop it up with their parents. At least, I don't think
there was formal classes on that particular day in WW history. :D
