] | If you use library[`find-dired+.el`](https://www.emacswiki.org/emacs/download/find-dired%2b.el) then you can use command **`find-time-dired`**. (You can also call it from Lisp or use part of its code, if you prefer.)

Here'... | Another option, and probably the most direct and best answer to my specific question, is `find-dired` with an argument of `-ctime +NDAYS`. Then in the resulting dired buffer, do `* t` to mark all the files (presuming you haven't marked any yet; `* t` toggles the marked state of all the files in the dired buffer.)
