Is it possible to find out the date a page was created?

I need to find out the date a page on my website was created. I've asked SquareSpace but they have said not. I don't believe it's not part of the metadata. Ideally, if you can find the dates a page was modified too, that would be great. Any ideas?

@GaryMP - You can pull a "last updated" value from the page source. Right click and view page source on the page you're curious about, then search for "data-updated-on", which turns up at a few spots in the html. This will show a value in system time (like "1567008451882"). There's converters online that'll swap this into a readable date & time. If I run that value through https://www.epochconverter.com/ I get this:

Which matches the last time I updated that page. That said, I don't think you can get a "Created On" date from the page source by default, though this guide for pulling published dates using Google seems fairly accurate: https://www.maketecheasier.com/find-out-webpage-published-date/
