How to Get the Current Date in JavaScript

How do I get the current date in JavaScript?

Use new Date() to generate a new Date object containing the current date and time.

var today = new Date();

var dd = String(today.getDate()).padStart(2, '0');

var mm = String(today.getMonth() + 1).padStart(2, '0'); //January is 0!

var yyyy = today.getFullYear();

today = mm + '/' + dd + '/' + yyyy;

document.write(today);

Getting current date and time in JavaScript

.getMonth() returns a zero-based number so to get the correct month you need to add 1, so calling .getMonth() in may will return 4 and not 5.

So in your code we can use currentdate.getMonth()+1 to output the correct value. In addition:

• .getDate() returns the day of the month <- this is the one you want
• .getDay() is a separate method of the Date object which will return an integer representing the current day of the week (0-6) 0 == Sunday etc

so your code should look like this:

var currentdate = new Date(); 
var datetime = "Last Sync: " + currentdate.getDate() + "/"
                + (currentdate.getMonth()+1)  + "/" 
                + currentdate.getFullYear() + " @ "  
                + currentdate.getHours() + ":"  
                + currentdate.getMinutes() + ":" 
                + currentdate.getSeconds();

JavaScript Date instances inherit from Date.prototype. You can modify the constructor's prototype object to affect properties and methods inherited by JavaScript Date instances

You can make use of the Date prototype object to create a new method which will return today's date and time. These new methods or properties will be inherited by all instances of the Date object thus making it especially useful if you need to re-use this functionality.

// For todays date;
Date.prototype.today = function () { 
    return ((this.getDate() < 10)?"0":"") + this.getDate() +"/"+(((this.getMonth()+1) < 10)?"0":"") + (this.getMonth()+1) +"/"+ this.getFullYear();
}

// For the time now
Date.prototype.timeNow = function () {
     return ((this.getHours() < 10)?"0":"") + this.getHours() +":"+ ((this.getMinutes() < 10)?"0":"") + this.getMinutes() +":"+ ((this.getSeconds() < 10)?"0":"") + this.getSeconds();
}

You can then simply retrieve the date and time by doing the following:

var newDate = new Date();
var datetime = "LastSync: " + newDate.today() + " @ " + newDate.timeNow();

Or call the method inline so it would simply be -

var datetime = "LastSync: " + new Date().today() + " @ " + new Date().timeNow();

Get Current Date using JS

You should be using getDate() and not getDay(). The latter returns the zero-based day of the week (starting Sunday). You want to get the date of the month.

In order to ensure you get double digits for the month and day, you need to convert those numbers to string first, and then use String.prototype.padStart.

const getDate = () => {
  const newDate = new Date();
  const year = newDate.getFullYear();
  const month = newDate.getMonth() + 1;
  const d = newDate.getDate();
  
  return `${month.toString().padStart(2, '0')}/${d.toString().padStart(2, '0')}/${year}`;
}

console.log(getDate());

How do I get the current date in JavaScript?

Use new Date() to generate a new Date object containing the current date and time.

var today = new Date();

var yyyy = today.getFullYear();

today = mm + '/' + dd + '/' + yyyy;

document.write(today);

How to get current formatted date dd/mm/yyyy in Javascript and append it to an input

I hope this is what you want:

const today = new Date();
const yyyy = today.getFullYear();
let mm = today.getMonth() + 1; // Months start at 0!
let dd = today.getDate();

if (dd < 10) dd = '0' + dd;
if (mm < 10) mm = '0' + mm;

const formattedToday = dd + '/' + mm + '/' + yyyy;

document.getElementById('DATE').value = formattedToday;

How to get current date in jQuery?

Date() is not part of jQuery, it is one of JavaScript's features.

See the documentation on Date object.

You can do it like that:

var d = new Date();

var month = d.getMonth()+1;
var day = d.getDate();

var output = d.getFullYear() + '/' +
    (month<10 ? '0' : '') + month + '/' +
    (day<10 ? '0' : '') + day;

See this jsfiddle for a proof.

The code may look like a complex one, because it must deal with months & days being represented by numbers less than 10 (meaning the strings will have one char instead of two). See this jsfiddle for comparison.

How to get current date and time as a constant?

your constant should be initialize at the loading of the page and not on the http request

you should store the value in a variable and not recall moment() when you perform your http request

const time = moment().format("MMMM DD YYYY, hh:mm:ss");

function displayInitTime() {
  console.log(time);
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.29.1/moment.min.js" integrity="sha512-qTXRIMyZIFb8iQcfjXWCO8+M5Tbc38Qi5WzdPOYZHIlZpzBHG3L3by84BBBOiRGiEb7KKtAOAs5qYdUiZiQNNQ==" crossorigin="anonymous" referrerpolicy="no-referrer"></script>

<button onClick="displayInitTime()">click me</button>

How can I add 1 day to current date?

To add one day to a date object:

var date = new Date();

// add a day
date.setDate(date.getDate() + 1);

How do I get the current time only in JavaScript

var d = new Date("2011-04-20T09:30:51.01");
d.getHours(); // => 9
d.getMinutes(); // =>  30
d.getSeconds(); // => 51

or

var d = new Date(); // for now
d.getHours(); // => 9
d.getMinutes(); // =>  30
d.getSeconds(); // => 51
