Change start season date FM14

Hi! I'm new in the forum and i'm spanish. Only one question, How can I change the start season date of july 2013 to july 2014???

Thanks

The only real way I know to do this is to create a manager and leave him unemployed, then go on holiday until July 2014. When you get to that date retire your created manager and add yourself in at that time and you'll be starting from July 2014.
