window.onload = function(){
var y = new Date();
var year = document.createElement('select');
for(x= y.getFullYear();x>=1900; x--)
{
var yyyy = document.createElement('option');
yyyy.innerHTML = x;
year.appendChild(yyyy);
}
document.body.appendChild(year);

var mon = document.createElement('select');
var month = {'1':'Jan','2':'Feb','3':'Mar','4':'Apr','5':'May','6':'Jun',
'7':'Jul','8':'Aug','9':'Sep','10':'Oct','11':'Nov','12':'Dec'};

for(x= 1;x<=12; x++)
{
var mm = document.createElement('option');
mm.innerHTML = month[x];
mon.appendChild(mm);
}
document.body.appendChild(mon);

var day = document.createElement('select');
for(x= 1;x<=31; x++)
{
var dd = document.createElement('option');
dd.innerHTML = x;
day.appendChild(dd);
}
document.body.appendChild(day);

var go = document.createElement('button');
go.innerHTML = "GO";
//go.setAttribute('onclick', 'call();')
document.body.appendChild(go);
go.onclick = call;
function call(){
var sel = document.getElementsByTagName('select');
var ms = '';
for(var key in month){
if(month[key] == sel[1].value){
ms = key - 1;
}
}
let d = new Date (sel[0].value, ms, sel[2].value);

var day = d.getDay();
switch (day){
case 0:
day = "Sunday";

Answer 9

with Web Storage API

Storing a Value: localStorage.setItem("key1", "value1");
Getting a Value: //this will print the value

by storing u can use time settings
