Highlight specific dates in Jquery UI Datepicker

Question

I've read the other questions like this here, but none does exactly what I want.

I want to add a class to all the days between two dates. The dates will be set in variables.

Any thoughts?

You need to implement the beforeShowDay event for the datepicker :

The function takes a date as a parameter and must return an array with [0] equal to true/false indicating whether or not this date is selectable, [1] equal to a CSS class name(s) or '' for the default presentation, and [2] an optional popup tooltip for this date. It is called for each day in the datepicker before it is displayed.

So you need to do something like:

$("#datepicker").datepicker({
    beforeShowDay: function(d) {
        var a = new Date(2012, 3, 10); // April 10, 2012
        var b = new Date(2012, 3, 20); // April 20, 2012
        return [true, a <= d && d <= b ? "my-class" : ""];
    }
});

Demo:

 $(function() { $("#datepicker").datepicker({ beforeShowDay: function(d) { // a and b are set to today ± 5 days for demonstration var a = new Date(); var b = new Date(); a.setDate(a.getDate() - 5); b.setDate(b.getDate() + 5); return [true, a <= d && d <= b ? "my-class" : ""]; } }); }); 

 @import url("https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/themes/blitzer/jquery-ui.min.css"); .my-class a { background: #FC0 !important; } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/jquery-ui.min.js"></script> <input id="datepicker">
