Fits those three numbers, which makes me suspect that's it.

May ** not ** be the day of the week but those three dates follow that pattern.

Oh my goodness, that's awesome! That must be it, because the built-in Date function uses exactly the same display, with the day of week showing in the exponent area. So the Version screen just called the Date code to display the version date... and the day of week is an unnecessary byproduct. Very cool! Thanks, Gene!
