Date Evaluation in JS

I need to validate a credit card expiry date, I have the javascript code but I don't know how to customize it for my need.
this is my code, I only need the date in a mm/yy format but this code has the date format in mm/dd/yyyy.
var date = document.getElementById('date');
function checkValue(str, max) {
if (str.charAt(0) !== '0' || str == '00') {
var num = parseInt(str);
if (isNaN(num) || num <= 0 || num > max) num = 1;
str = num > parseInt(max.toString().charAt(0))
&& num.toString().length == 1 ? '0' + num : num.toString();
};
return str;
};
date.addEventListener('input', function(e) {
this.type = 'text';
var input = this.value;
if (/\D\/$/.test(input)) input = input.substr(0, input.length - 3);
var values = input.split('/').map(function(v) {
return v.replace(/\D/g, '')
});
if (values[0]) values[0] = checkValue(values[0], 12);
if (values[1]) values[1] = checkValue(values[1], 31);
var output = values.map(function(v, i) {
return v.length == 2 && i < 2 ? v + ' / ' : v;
});
this.value = output.join('').substr(0, 14);
});

Zeller's algorithm

I need to find which day it is when I put a date in the input using Zeller's algorithm. So this is how I've come so far. I've used the base code from my teacher, but when I put today's date in, it comes out Friday when it should be Wednesday instead.
var print = document.getElementById("print");
print.onclick = function () {
var D = document.getElementById("date").value;
var M = document.getElementById("month").value;
var Y = document.getElementById("year").value;
var C = document.getElementById("twoFirst").value;
var K = document.getElementById("twoLatest").value;
pOutput.innerHTML = dagFunction(D, M, Y, C, K);
}
function dagFunction(D, M, Y, C, K) {
if (M==1 || M==2) {
M+=12;
Y--;
return (M, Y)
}
var X = 2.6 * M - 5.39
if (X < 0) {
X = Math.ceil(X) // X skal rundes opp
}
else {
X = Math.floor(X) // X skal rundes ned
}
Y = Math.floor(K/4)
var Z = Math.floor(C/4)
var S = X + Y + Z + D + K - 2 * C
var R = S % 7
if (R==0) {
return "Søndag"
}
else if (R==1) {
return "Mandag"
}
else if (R==2) {
return "Tirsdag"
}
else if (R==3) {
return "Onsdag"
}
else if (R==4) {
return "Torsdag"
}
else if (R==5) {
return "Fredag"
}
else if (R==6) {
return "Lørdag"
}
}

How do i call a javascript function to execute after another script ends

I am trying to call function sumWH after the completion of the function sumMon1. Both functions get the text from labels, sum up their values, and update a counter label. The code that I have attempted to use to call sumHW after sumMon1 is below and does not work.
$.when(sumMon1()).done(function () {
sumWH();
});
the sum functions look like this:
<script>
$.when(sumMon1()).done(function () {
sumWH();
});
function sumWH() {
alert(event.target);
//Get Friday AM Out Value
var a = parseInt($('[id$="lblWeek1FridayTotalHrs"]').val(), 10) || 0;
//Get Friday AM IN Value
var b = parseInt($('[id$="lblWeek2FridayTotalHrs"]').val(), 10) || 0;
//Get Friday PM Out Value
var c = parseInt($('[id$="lblWeek1SaturdayTotalHrs"]').val(), 10) || 0;
//Get Friday AM IN VALUE
var d = parseInt($('[id$="lblWeek2SaturdayTotalHrs"]').val(), 10) || 0;
//Get Friday AM Out Value
var e = parseInt($('[id$="lblWeek1SundayTotalHrs"]').val(), 10) || 0;
//Get Friday AM IN Value
var f = parseInt($('[id$="lblWeek2SundayTotalHrs"]').val(), 10) || 0;
//Get Friday PM Out Value
var g = parseFloat($('[id$="lblWeek1MondayTotalHrs"]').val(), 10);
//Get Friday AM IN VALUE
var h = parseInt($('[id$="lblWeek2MondayTotalHrs"]').val(), 10) || 0;
//Get Friday AM Out Value
var i = parseInt($('[id$="lblWeek1TuesdayTotalHrs"]').val(), 10) || 0;
//Get Friday AM IN Value
var j = parseInt($('[id$="lblWeek2TuesdayTotalHrs"]').val(), 10) || 0;
//Get Friday PM Out Value
var k = parseInt($('[id$="lblWeek2WednesdayTotalHrs"]').val(), 10) || 0;
//Get Friday AM IN VALUE
var l = parseInt($('[id$="lblWeek1WednesdayTotalHrs"]').val(), 10) || 0;
//Get Friday AM Out Value
var m = parseInt($('[id$="lblWeek2ThursdayTotalHrs"]').val(), 10) || 0;
//Get Friday AM IN Value
var n = parseInt($('[id$="lblWeek1ThursdayTotalHrs"]').val(), 10) || 0;
var result = a + b + c + d + e + f + g + h + i + j + k + l + m + n;
if (result > 0 && result < 81 && !isNaN(result)) {
$('[id$="txtTotalHours"]').html(result);
} else if (result == 0) {
$('[id$="txtTotalHours"]').html(0);
} else if (isNaN(result)) {
$('[id$="txtTotalHours"]').html(result);
}
}
</script>
<script>
$(document).ready(function () {
sumMon1();
$('[id$="txtWeek1MondayPM_OUT"], [id$="txtWeek1MondayAM_OUT"]').on("blur", function () {
sumMon1();
});
});
function sumMon1() {
//Get Monday AM Out Value
var Out2Dec = $('[id$="txtWeek1MondayAM_OUT"]').val();
//split dec and whole AM OUT
var OutAmDec = Out2Dec % 1;
var OutAMWhole = Math.floor(Out2Dec);
if (OutAMWhole < 12 && OutAMWhole != 0 && !isNaN(OutAMWhole)) {
OutAMWhole += 12;
}
//Get Monday AM IN Value
var In2Dec = $('[id$="txtWeek1MondayAM_IN"]').val();
//split dec and whole AM IN
var InAmDec = In2Dec % 1;
var InAmWhole = Math.floor(In2Dec);
//Get Monday PM Out Value
var Out1Dec = $('[id$="txtWeek1MondayPM_OUT"]').val();
//split dec and whole PM OUT
var OutPmDec = Out1Dec % 1;
var OutPMWhole = Math.floor(Out1Dec);
if (OutAMWhole < 12 && OutAMWhole != 0 && !isNaN(OutAMWhole)) {
OutPMWhole += 12;
}
//Get Monday AM IN VALUE
var In1Dec = $('[id$="txtWeek1MondayPM_IN"]').val();
//split dec and whole PM IN
var InPmDec = In1Dec % 1;
var InPMWhole = Math.floor(In1Dec);
//calculate times
var InAmVal = (InAmWhole * 60) + (InAmDec * 100);
var OutAmVal = (OutAMWhole * 60) + (OutAmDec * 100);
var InPmVal = (InPMWhole * 60) + (InPmDec * 100);
var OutPmVal = (OutPMWhole * 60) + (OutPmDec * 100);
var Difference = (OutAmVal - InAmVal) + (OutPmVal - InPmVal);
var result = Difference / 60;
//display result
if (result > 0 && !isNaN(result)) {
$('[id$="lblWeek1MondayTotalHrs"]').html(result.toFixed(2));
} else {
var value2 = (result.toFixed(2) * -1);
$('[id$="lblWeek1MondayTotalHrs"]').html(value2);
}
}
</script>
The sum functions are located in separate script tags. sumMon1 is set to go on blur from a series of textboxes.
Is this there a way to make this function work or is there a better way to accomplish this?

jQuery.when is for async functions.
async is something like setInterval or jQuery.ajax.
And except async stuff, JavaScript (Or almost any other languages as well) run codes from top to the bottom sequentially.
Your code is not using asynchronous things. so simply do
sumMon();
sumWH();

How to get String output as in single quote in javascript

Advance thanks, Question looks like simple but i could not able to find the solution.
function sumStrings(a, b)
{
return +a + +b;
}
sumStrings('1','2') //=>3
Expected output
sumStrings('1','2') // => '3'

After addition, add ' to beginning and end.
function sumStrings(a, b){
return "'" + (Number(a) + Number(b)) + "'";
}
console.log(sumStrings('1','2'));

function sumStrings(a, b) {
// Separate decimal part here
var pointa = a.indexOf(".");
var pointb = b.indexOf(".");
var deca = pointa != -1 ? a.substring(pointa + 1) : "0";
var decb = pointb != -1 ? b.substring(pointb + 1) : "0";
if (deca.length < decb.length)
deca += (Math.pow(10, decb.length - deca.length)).toString().substring(1);
else
decb += (Math.pow(10, deca.length - decb.length)).toString().substring(1);
var inta = pointa != -1 ? a.substring(0, pointa) : a;
var intb = pointb != -1 ? b.substring(0, pointb) : b;
// console.log(deca + " " + decb);
var decc = addBigInt(deca, decb);
var intc = addBigInt(inta, intb);
if (decc.length > deca.length) {
intc = addBigInt(intc, "1");
decc = decc.substring(1);
}
var lastZero = decc.length - 1;
while (lastZero >= 0 && decc[lastZero] == "0") {
lastZero--;
}
if (lastZero >= 0)
return intc + "." + decc.substring(0, lastZero + 1);
else
return intc;
}
function addBigInt(a, b) {
var inda = a.length - 1;
var indb = b.length - 1;
var c = [];
const zero = "0".charCodeAt(0);
var carry = 0;
var sum = 0;
while (inda >= 0 && indb >= 0) {
var d1 = a.charCodeAt(inda--) - zero;
var d2 = b.charCodeAt(indb--) - zero;
sum = (d1 + d2 + carry);
carry = Math.floor(sum / 10);
sum %= 10;
c.unshift(sum);
}
if (inda >= 0) {
while (carry && inda >= 0) {
sum = a.charCodeAt(inda--) - zero + carry;
c.unshift(sum % 10);
carry = Math.floor(sum / 10);
}
c.unshift(a.substring(0, inda + !carry));
} else {
while (carry && indb >= 0) {
sum = b.charCodeAt(indb--) - zero + carry;
c.unshift(sum % 10);
carry = Math.floor(sum / 10);
}
c.unshift(b.substring(0, indb + !carry));
}
if (carry)
c.unshift(carry);
return c.join("");
}
console.log(sumStrings("1","2"));
console.log(sumStrings("800","9567"));
console.log(sumStrings("99.1","1"));
console.log(sumStrings("00103","08567"));
console.log(sumStrings("50095301248058391139327916261.5","81055900096023504197206408605"));

If you want to escape the single quote, you can try to add a backslash before the single quote.
i.e.
var x = '\'5\'';

With the new template literal you can try this:
a=`'5'`;
console.log(a);
