You can parse the initial date, feed it to a date object, substract it with the current time to get a millisecond difference, and then divide it by the number of milliseconds in a day.

var checkindatestr = "28-07-2011";
var dateParts = checkindatestr.split("-");

var checkindate = new Date(dateParts[2], dateParts[1] - 1, dateParts[0]);
var now = new Date();
var difference = now - checkindate;
var days = difference / (1000*60*60*24);

alert(days);

At the time of writing this gives -7.5. It's a negative number because the date is in the future. If you want a positive number, just swap the variables in the substraction. If you want a round number, just use Math.round.

You can parse your first date as described in this thread: Parse DateTime string in JavaScript

var strDate = "28-07-2011";
var dateParts = strDate.split("-");

var date = new Date(dateParts[2], (dateParts[1] - 1) ,dateParts[0]);

And then pare the two dates as asked here: Compare two dates with JavaScript
