I think that I found an error in it, though it shouldn't affect anyone's ability to use it for most purposes.
There is an overlap in the calendar: December 31, 99 (3 Shevat 3860) is on a Friday. The next day, January 1, 100 (4 Shevat 3860) is also on Friday.
I believe that the Jan. 1 day is correct, as it is consistent with today (Nov 3, 2008) being a Monday. But this affects the ability to look up earlier dates (e.g., past dates of Birchas Hachamah, as I was doing when I discovered this.)
I think that I figured out what is causing the error, though it doesn't change the fact that days of the week before secular year 100 will be off.
Basically, it looks like the calendar is calculating days of the week during the 2 digit years as if they were in the 1900's, so Dec. 99 will show up with the same structure as Dec. 1999 even though it should actually have all days of the month fall out one day of the week earlier.
For example, Dec 31, 99, which actually fell out on a Thursday, shows up as Friday -- which is the correct day of the week for Dec 31, 1999.
