Make Jquery calculates difference in % between 2 dates

This project was left over by a previous Freelancer. Here it goes: 2 dates are given for a work completion Percentage bar (bootstrap UI): Start Date, End Date By taking into consideration Todays date a percentage of Completion is rendered which modifies the Width of the class .BAR element and writes into InnerHTML of the element the Percentage Value. Problem is: The math needs some critical adjustments. BUG 1: 2011-07-02 2012-09-02 Result = 126% (Wrong the percentage cannot go over 100% maximum) BUG 2: 2012-07-02 2012-09-02 Result = Nothing (It's suppose to output 100%) BUG 3: I'm not quite sure the math is accurate here.
