Check if weekend exist in date range using javascript

Question

Wondering if anyone has a solution for checking if a weekend exist between two dates and its range.

var date1 = \'Apr 10, 2014\';
var date2 = \'Apr 14, 2014\

Here's what I'd suggest to test if a weekend day falls within the range of two dates (which I think is what you were asking):

function containsWeekend(d1, d2)
{
    // note: I'm assuming d2 is later than d1 and that both d1 and d2 are actually dates
    // you might want to add code to check those conditions
    var interval = (d2 - d1) / (1000 * 60 * 60 * 24); // convert to days
    if (interval > 5) {
        return true;    // must contain a weekend day
    }
    var day1 = d1.getDay();
    var day2 = d2.getDay();
    return !(day1 > 0 && day2 < 6 && day2 > day1);
}

If you need to check if a whole weekend exists within the range, then it's only slightly more complicated.
