Dont worry I have not got a clue when they go back either!!! I just know the old saying Fall (autuam) back Spring forward! So im going to guess somewhere end of sept begining of october?
The clocks always seem to be going backwards and forwards, it's so annoying because i always forget and miss it and am late / early for everything... >__<
i think it may be middle of october? it always seems to happen a week or two before my birthday as far as i can remember (my b-day is october 30th) but dont quote me on that! lol
