OK! My first attempt to attach something, we'll see how it goes.
I must toot my own horn here, I'm in the credits of this thing. I gave the guy the roll over formula so the moon phases would be accurate as you carry over years. Doesn't sound like much, but without that you can't just type in the year and have it work, you need to go year by year.
SO yay me!
Edit: This is the kind of thing that gets you tossed out of the house: thanks to my lovely wife for filling in the roll of years from FRCS...
