Hmm. It seems like every time I go through the MJD/JD thing that .5 day
thing pops up. Of course, it's been long enough since I last solved the
problem I can't remember the exact details with the .5 day. Just off
the top of my head I do remember that the formula is extremely sensitive
to all of those casts and parens controlling the order of evaluation.
Check those out.
I have to run up to Home Depot then finish fixing the side gate before
the sun sets here in CA. After that I'll jump on this problem with you
- we'll get it working.
