Insert all remaining dates until a specific date into a slider

Question

I am using a bootstrap slider for an interest calculator, where I can slide an amount from 0 - 15.000 DKK and another slider that contains remaining days until a specific dates.

Those two slider will calculate the interest when money is inserted at specific dates.

My problem now is that I want the slider tooltip to show sequential dates, i.e at page load the slider will start on todays date (3 March 2016), then when I slide it 4 steps the tooltip should show 7 March 2016, and if I slide it 30 steps it should show 2 April.

The slider is initialised with this:

$(".date").slider({
    tooltip: 'always',
    min: 1,
    max: daysRemaining,
    step: 1,
    value: daysRemaining,
    formatter: function (daysRemaining) {
       DateOutputFunction here
     }
 });

daysRemaining are found using moment.js

var today = moment();
var lastDate = moment("20161212");
var daysRemaining = lastDate.diff(today, "days");

You can use moment add and moment format to get what you need, for example:

var today = moment();
var lastDate = moment("20161212");
var daysRemaining = lastDate.diff(today, "days");

$(".date").slider({
    tooltip: 'always',
    min: 1,
    max: daysRemaining,
    step: 1,
    value: daysRemaining,
    formatter: function (value) {
        var today = moment();
        var day = today.add(value, "days");
        return day.format("D MMMM YYYY");
    }
 });

.slider{
  margin: 50px;
}
