JavaScript Date now() Method

In this article, we will learn about the Date now() method in Javascript. The date.now() method is used to return the number of milliseconds elapsed since January 1, 1970, 00:00:00 UTC. Since now() is a static method of Date, it will always be used as Date.now(). 

Syntax:

var A = Date.now();

Parameters: This method does not accept any parameter. 

Return Values: It returns the number of milliseconds elapsed since January 1, 1970, 00:00:00 UTC.

Please refer to the JavaScript Get Date Methods article for other Date methods in detail.

More codes for the above method are as follows: 

Example 1: The below example illustrates the Date now() method.

Javascript

<script>

  // Use of method Date.now()
  var A = Date.now();

  // Printing the number of millisecond elapsed
  document.write("The time elapsed in millisecond is: " + A);
</script>

Output:

The time elapsed in millisecond is: 1529644667834

Example 2: This example illustrates getting the current date using the Date.now() method.

Javascript

<script>

  // Use of Date.now() method
  var d = Date(Date.now());

  // Converting the number of millisecond
  // in date string
  a = d.toString()

  // Printing the current date
  document.write("The current date is: " + a)
</script>

Output:

The current date is: Fri Jun 22 2018 10:54:33 
GMT+0530 (India Standard Time)

Example 3: The Date(Date.now()) is the same as Date(), so the same result can be achieved i.e, the current date using the following code.

Javascript

<script>
  // Using Date() method
  var d = Date();

  // Converting the number value to string
  a = d.toString()

  // Printing the current date
  document.write("The current date is: " + a)
</script>

Output:

The current date is: Fri Jun 22 2018 11:02:01 
GMT+0530 (India Standard Time)
