Using JavaScript to Get Date Format in yyyy mm dd

We can use JavaScript to get the date in the format of yyyy mm dd by making use of the JavaScript toLocaleString() method. There are many configurations we can utilize with the toLocaleString() method to display the date how we want. One of these configurations will get the format we want.

Note that we will use the toLocaleDateString() method is our examples below. This method works the same way as the toLocaleString() method, except that it will just display the date, and NOT the time.

Here is the code to get the date in the format of yyyy-mm-dd. We will explain how we got this below.

var currDate = new Date();
var localDate1 = currDate.toLocaleDateString('en-CA');

console.log(localDate1);

#Output
2022-08-31

The JavaScript toLocaleString method will take a date object and return the date as a string using the local settings from your computer.

var currDate = new Date();
var localDate = currDate.toLocaleString();

The date is returned in a much friendlier format for the user than what the Date() method returns. The outputs of currDate and localDate from above are displayed as follows:

So if we wanted to display the date in the yyyy-mm-dd format, we can use different options for parameters in the toLocaleString() method. A list of these options can be found here.

So to get the date in the format of yyyy-mm-dd, we can simply use the Canadian English language format as the only parameter in the toLocaleString() method. Let’s see this below.

var currDate = new Date();
var localDate2 = currDate.toLocaleDateString('en-CA');

console.log(localDate2);

#Output
2022-08-31

If we want to display the date with slashes instead of hyphens, yyyy/mm/dd, we can use the following parameter:

var currDate = new Date();
var localDate3 = currDate.toLocaleDateString('en-ZA');

console.log(localDate3);

#Output
2022/08/31

There are other languages we can put as the parameter that would also display the date in the yyyy-mm-dd format as well, we just chose the first one we saw down the list.

Another very simple way to display the date in the yyyy-mm-dd format is to simply get the year, month, and date in the format we want, and combine them. Here is some code below to show how easily this can be done.

var currDate = new Date();
var year = currDate.toLocaleString('en-US', { year: 'numeric'});
var month = currDate.toLocaleString('en-US', { month: '2-digit'});
var day = currDate.toLocaleString('en-US', { day: '2-digit'});

var dateInYYYYMMDD = year + "-" + month + "-" + day;

console.log(dateInYYYYMMDD);

#Output
2022-08-31

Displaying the Current Date and Time in YYYY-MM-DD using the JavaScript toLocaleString Method

Below we will provide code to get the current date in JavaScript, and let the user see it in a friendly format when they click a button.

Today's Date is: 

We will simply get the Date with the Date() method, and use the toLocaleString() method and some parameter options to display the date and time nicely. Here is the simple JavaScript code:

function genNewDate(){
  var currDate = new Date();
  var localDate = currDate.toLocaleDateString('en-CA');
  document.getElementById("theDate").innerHTML = localDate;
}

The final code and output for this example is below:

Code Output:
