OP sounds like they may not be a member but are looking for a rental. In that case, you should start looking on the rent trade board here no later than Jan 09 to find someone to rent from who can then call to make the ressie in Feb 09 for Jan 2010.
And Kristenrice, you cannot call April 4, 2009 to reserve April 4-10, 2010, and yes, I also often have a problem with math when it comes to figuring out when I am 11 (not 12) months out.
