disable past dates on datepicker

Question

How to disable past dates from the current date on a datetimepicker? I tried few posts for similar question but was unable to achieve it, Below is what I tried

Answer 1

minDate: dateToday Or minDate: '0' is the key here. Try to set the minDate property.

$(function() {
    $( "#datepicker" ).datepicker({
        numberOfMonths: 2,
        showButtonPanel: true,
        minDate: dateToday // minDate: '0' would work too
    });
});
