I don't know, maybe my calculations are wrong, but mIRC says, that this year, we have 52wks and 1day:
$duration($calc($ctime(31/12/2008) - $ctime(01/01/2008))) = 52wks 1day
BUT THIS IS INCORRECT! This all messes my trivbot, that uses mirc time to get number of week... This is leap year!
Does mIRC have forgotten about it? or maybe Khaled'n'friends? :P
