HTML DOM lastModified Property

Last Updated : 10 Aug, 2026

The DOM lastModified property in HTML is used to return the date and time of the current document that was last modified. This property is read-only. This property returns a string that contains the date and time when the document was last modified. 

Syntax

document.lastModified

Example: In this example, we will use the lastModified property

html 
<!--Driver Code Starts-->
<!DOCTYPE html>
<html>

<head>
    <title>
        DOM lastModified Property
    </title>
</head>

<body style="text-align:center">
    <h1 style="color:green;">
        GeeksForGeeks
    </h1>
    <h2>
        DOM lastModified Property
    </h2>
<!--Driver Code Ends-->

    <button onclick="geeks()">
        Submit
    </button>
    <p id="sudo"></p>
    <script>
        /* Function to use lastModified property */
        function geeks() {
            let x = document.lastModified;
            document.getElementById("sudo").innerHTML = x;
        }
    </script>

<!--Driver Code Starts-->
</body>

</html>
<!--Driver Code Ends-->
  • The code uses the document.lastModified property to get the date and time when the current HTML document was last modified and displays it inside the <p> element.
  • The geeks() function runs when the Submit button is clicked, retrieves the last modified date, and updates the webpage content using innerHTML.
