Question

Any idea why this function doesn’t work properly in Internet Explorer?

function days_between(check_in, check_out)
{
    var oneDay = 24*60*60*1000; 
    var firstDate = new Date(check_in);
    var secondDate = new Date(check_out);    
    var diffDays = Math.abs((firstDate.getTime() - secondDate.getTime())/(oneDay));
    return diffDays;
}

in internet explorer it shows NaN as result.

im calling this function in this date format

var check_in = "2012-02-09";
var check_out = "2012-02-12"; 
var range = days_between(check_in, check_out);

Regards

The date format you’re passing (yyyy-mm-dd) isn’t supported by Date. See the note here that says it must be in a format parsable by parse. See here for acceptable parse formats: https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Date/parse
