This is the guided tour page: https://www.gnu.org/software/emacs/tour/

On the guided tour page, there's this line:
"M-x phases-of-moon  Shows upcoming quarters of the moon."

Launching Emacs with "emacs -Q" and doing an apropos-command search via 
"C-h a" for "moon" didn't give any results. Doing another search for 
"phases" showed "lunar-phases".

I think "M-x phases-of-moon" is meant to be "M-x lunar-phases": 
https://www.gnu.org/software/emacs/manual/html_node/emacs/Lunar-Phases.html

My output from "M-x emacs-version":
GNU Emacs 29.2 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.40, 
cairo version 1.18.0)

Please let me know if there's a better way to send something this small!

It was originally indeed called phases-of-moon, was renamed in 2008,
and the obsolete alias kept for backward compatibility was removed in
2014.

Thanks, I fixed the Guided Tour page to mention the current name of
the command, and I'm therefore closing this bug.
