Use the beforeShowDay callback as shown in this post.

OK. That works fine, but it seems to be a little "overwork" to have to define every date. I whish there was a way to define a date span (i.e. 2012-05-01 - 2012-05-15). Is it possible?

Of course, just replace the test with your own code:

1. $('#date').datepicker({beforeShowDay: blackoutDates});
2. 
   
3. var blackoutRange = [new Date(2012, 5-1, 1, 0, 0, 0, 0).getTime(),
4.       new Date(2012, 5-1, 15, 23, 59, 59, 999).getTime()];
5. 
   
6. function blackoutDates(date) {
7.       var blackout = date.getTime() >= blackoutRange[0] &&
8.             date.getTime() <= blackoutRange[1];
9.       return [!blackout, blackout ? 'blackout' : ''];
10. }
