HP12C: my screen show D.MY in display. What does this mean? Is it important?

I see i can erase it w/ the blue g button and 4 or 5, depending on D.MY or M.DY.  Does it matter?>

Hi,

It depends on how you prefer to enter the date when using date functions e.g. days between dates.

When M.DY is selected, enter 23 September 2014 as 9.232014

When D.MY is selected, it is entered as 23.092014

Regards.

You're welcome. By the way, there are some examples on the back of the calculator.

Enjoy your calculator 🙂
