Although some websites list a creation date on the page, not all of them do. This date is typically required for reference purposes---when working on a school project, for example. You may obtain the required information by referencing either the Internet Archive or Whois service, which works with the Internet Corporation for Assigned Names and Numbers (ICANN). These online institutions provide information about registered domain names for public knowledge.
Launch the Internet Archive's "Wayback Machine" page in your browser.
Type the web page address in the text field that appears. Click the "New! Updated Interface" button or select the "Class Interface" option underneath the field.
Click the "Take Me Back" button to view the site's creation date on the page that displays. If you selected the new interface in the previous step, this data is found in the top-right corner.
Bring up the Whois website.
Enter the domain in the text field that displays.
Click the "lookup" button. Scroll through the page that appears until you find the "Created" entry.
You also have the option to contact the website creator directly to ask about the origination date. Look for an "About" or "Contact" page, or scroll to the very bottom and see if an e-mail link is displayed.
