What steps will reproduce the problem?

Start and end date pickers but only dates in the past selectable

Please provide a URL to a page displaying the problem.

What version of the datepicker are you using? On what operating system? And 
Which Browser?

Please provide any additional information below.
I use your demo script "Start and end date pickers" and it works well. But I 
would like to have only past days selectable. How can I do this?

You will have to set the startDate and endDate parameters in the definition of 
your datepicker.

    $('.date-pick').datePicker(
    {
        clickInput: true,
        startDate: '2012-08-31', //Some date in the past
        endDate: '2014-01-20 00:00:00' //Some date, today in your case.
    }
