That 2004 page has an enticing link. Apparently referring to something related to the calendar, I note that somebody explains that "everything that we know is wrong". It's not surprising that twelve years later linkrot has set in and I can no longer reach the page those words linked to. But I really wish that I could. I've love to know what it was that I'd found worth a link, not to mention how whoever posted that page knows that everything we know is wrong.
