What would be the easy way of achieving such below? selected_date comes from django context as a python date :

<script type=text/javascript>

    var selected_year = {{ selected_date|date:Y }}

    var selected_month = {{ selected_date|date:m }} - 1;

    var selected_day = {{ selected_date|date:d}}

    var selected_date = new Date(selected_year, selected_month, selected_day);

    alert(selected_date);

</script>
