Problems in changing countdown

I want to change time to 28th May, but I am not getting how to do that.

! function(a) {
"use strict";
"function" == typeof define && define.amd ? define(["jquery"], a) : a(jQuery)
}(function(a) {
"use strict";

function b(a) {
if (a instanceof Date) return a;
if (String(a).match(g)) return String(a).match(/^[0-9]*$/) && (a = Number(a)), String(a).match(/\-/) && (a = String(a).replace(/\-/g, "/")), new Date(a);
throw new Error("Couldn't cast `" + a + "` to a date object.")
}

function c(a) {
var b = a.toString().replace(/([.?*+^$[\]\\(){}|-])/g, "\\$1");
return new RegExp(b)
}

function d(a) {
return function(b) {
var d = b.match(/%(-|!)?[A-Z]{1}(:[^;]+;)?/gi);
if (d)
for (var f = 0, g = d.length; g > f; ++f) {
var h = d[f].match(/%(-|!)?([a-zA-Z]{1})(:[^;]+;)?/),
j = c(h[0]),
k = h[1] || "",
l = h[3] || "",
m = null;
h = h[2], i.hasOwnProperty(h) && (m = i[h], m = Number(a[m])), null !== m && ("!" === k && (m = e(l, m)), "" === k && 10 > m && (m = "0" + m.toString()), b = b.replace(j, m.toString()))
}
return b = b.replace(/%%/, "%")
}
}

function e(a, b) {
var c = "s",
d = "";
return a && (a = a.replace(/(:|;|\s)/gi, "").split(/\,/), 1 === a.length ? c = a[0] : (d = a[0], c = a[1])), 1 === Math.abs(b) ? d : c
}

Instead of posting some library's code, read the docs. It's all in there!

$('#myCountDown').countdown('2017/05/28', function(event) {
  $(this).html(event.strftime('%w weeks %d days %H:%M:%S'));
});
