Website Published Date Tool helps you find the date a website was most recently indexed by Google's Search Engine.

This helps you identify the date a webpage was most recently updated, usually within a week of accuracy. This is ideal if you are unable to locate the date of the most recent update to a webpage on the page itself but need to cite it for purposes of an academic paper, etc.

Enter the URL of the webpage you need the date updated for and click "Search."
A new tab will open in your web browser showing a summary of the link you searched for along with the date it was most recently updated.
