John, it doesn’t “matter” when something is made. Since you sell your pieces, it makes sense you would not want a date on your items. I don’t sell mine presently, not sure I ever will. I make what I make for fun, love of it. I then either keep it, or give it to family who I make it for or who like it. As a result, I do date mine. I date mine so I know when I made something. By dating, I can also hopefully tell the progress I have made over time. As a relative newbie to the saw, it is good to see that progress. Maybe with more experience, that becomes less a need or reason.
