    "the last time it was "noon at noon" here was...12/12/12!"

    Coincidences have a tendency to multiply. I predict that you will see 12's everywhere in the next 12 hours. Dozens and dozens of times.

    Regarding the diagram that I posted, you can quickly shift it to to your longitude. It was drawn for my longitude here which is a bit more than 3.55 degrees east of the central meridian of the time zone (that being 75 W in the case of Eastern Time). If you live right on the central meridian of your time zone, shift the time scale along the bottom to the left left by by 14.2 minutes. If you do that, you'll find that the two halves of the analemma, split by the shift from Standard Time to Saving Time, are more or less centered on 12:00 and 13:00. If you live at any other longitude, take the difference in degrees from the central meridian and shift left by 14.2-(diff*4) where the difference, diff, is positive east of the central meridian and negative west. If your more than about 4 degrees west of the central meridian of your time zone, it's NEVER noon at noon, and "high noon" or Local Apparent Noon always falls after 12:00 o'oclock, possible quite a long time after. There are also many locations that fall in the gap between the two halves of the split analemma: Boston, eastern Massachusetts, and the state of Maine never see the Sun right on the meridian when the clock says 12:00.
