This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Avoid using it and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

The File.lastModifiedDate read-only property returns the last modified date of the file. Files without a known last modified date returns the current date .


var time = instanceOfFile.lastModifiedDate


A Date object.


// fileInput is a HTMLInputElement: <input type="file" multiple id="myfileinput">
var fileInput = document.getElementById("myfileinput");

// files is a FileList object (simliar to NodeList)
var files = fileInput.files;

for (var i = 0; i < files.length; i++) {
  alert(files[i].name + " has a last modified date of " + files[i].lastModifiedDate);


Though present in early draft of the File API spec, this property has been removed from it and is now non-standard. Use File.lastModified instead.
