Still now ICAI not announced about exam time table of May 2014, While preparing of time table it consider all the facts i.e public holidays etc.... If once time table announced then generally it not changed it but due the reasons said by you then it will change the examination date for the concern exam for the concern area only.
However let you think about it after announcement of examination time table for may 2014 attempt officially by ICAI then we discuss about it if required any.
So please avoid this type of thinks now and be concentrate on your studies and preparation. All The Best,
