How can you Get the Google cache age of any URL or web page?

1. Go to the Google search engine at https://www.google.com/.

2. In the search bar, enter the following query, replacing "example.com" with the URL of the web page you're interested in:

   ```

   cache:example.com

   ```

3. Press Enter or click the search icon.

4. Google will display the cached version of the web page, along with a "This is Google's cache of..." message at the top. Right below that message, you may see a date and time that indicates when the page was last crawled and cached by Google.
