I think I've found a glitch in excel that I would like to manipulate. I have
found that if I put the number "444" in a cell, Excel will convert this to
the month name "March" using customer formatting. When excel looks to the 444
number and I ask for "mmmm" it displays the month name of March. My question
is what number do I use for all twelve months. What number do I use for
September? Where do I find the number codes at?
