Halloween?? isnt that next month?

OK, so, today I watched "kerching" or however its spelt, which was all about Halloween.. continued tomorrow.. Which was then followed by one of the CBBC presenters dressed up as dracula fangs and stuff about something eles Halloweeny....

Um, its 26th September (My Dads birthday), so, err, isnt halloween still 31st Oct or did I miss a new change in life somewhere??
