It’s wrong and you can easily get a real answer in any spreadsheet app.
September 11, 2001 + 8647 days = May 15, 2025.
Very interesting. Thanks for the feedback.
I wonder if ChatGPT hallucinated the answer or why it gave the wrong one.
This is also why the FR community is so great. It is very good at vetting facts.
So, that DOES leave open the possibility that the 8647 shell meme was intentionally publicized on May 15.
And that suggests it was planned ahead and with malice aforethought.
