Answer 1

If you are comparing dates and don't want to include time, you can use something like:

// dateString is format DD-MM-YYYY
function isMoreThan7DaysHence(dateString) {

    // Turn string into a date object at 00:00:00
    var t = dateString.split('-');
    var d0 = new Date(t[2], --t[1], t[0]);

    // Create a date for 7 days hence at 00:00:00
    var d1 = new Date();
    d1.setHours(0, 0, 0, 0);
    d1.setDate(d1.getDate() + 7);

    return d0 >= d1;
}

Note that the hours for today's date must be zeroed.
