How to order date column in ascending and descending order?

Question

Good afternoon, I wanted to order a column in ascending or descending order I have a table (the photo attached)I was able to order the title field in ascending and descending order but now I wanted to order the column of dates(BEGINNING OF THE CYCLE).

follows in attachment the images of the codes. Obs: the beginning column of the cycle is ordering the dates until a certain line dps scrambles the rest of the dates.

Javascript code Function loadTable () {

var table = $('table#table-planos');

table.DataTable({
    "processing": true,
    serverSide: true,
    ajax: {
        url: "/plano/apis/past_cycles_info/",
