The beforeShowDay callback allows you to do this. It is a function that takes a Date as a parameter and returns an array with [0] being true if the date is selectable, false if not, [1] being a CSS class to apply to that date cell, [2] being an optional popup tooltip for the date.

1. $('#mydate').datepicker({beforeShowDay: highlightOdds});
2. 
   
3. function highlightOdds(date) {
4.       return [true, date.getDate() % 2 == 1 ? 'odd' : ''];
5. }

and CSS

1. .odd { background-color: yellow; }

Hi, I have another question
I want to change the date text in the cell, not the cell
the "beforeShowDay" function seems can just change the cell color, not text inside the cell
