ScottSmith_Harms Mr Wizzard Joined: Jan 2003 Posts: 42,714 Spokane Washington	Yes, I was mistaken. The 10,000 day calender In Galen's White Book shows 2905 as July 11 with 1970 at the top of the page, but below in fine print he does show 1969/1970 on the same page so it was an oversight on my part, July 11, 1969 it is.
