Hmmm... now I have to go back and look! (fingers crossed as well...)
Here's the formula that I last posted:
= 25569+(A2/3600+
DATE(A2/316^3+14,5,)-WEEKDAY(DATE(A2/316^3+14,5,))+25/24
<
5115+A2/86400
)*(
5115+A2/86400
<
DATE(A2/316^3+14,11,)-WEEKDAY(DATE(A2/316^3+14,11,))+25/24
)/24
I really made a mess of it. I moved the A2/3600 inside a parenthesis that
did not match with the last closing parenthesis. My results are completely
off now. That's one point for you! ;) If it's any excuse, I live about 90
minutes from Boston and haven't been getting much sleep this week. (Go
Sox!)
The Perl diehards must be pretty tired of us by now!
