It will return an "Invalid Input" argument. because it is outside the allowed range. This will also reset to the default 5 minute. Then turn your calculator off then back on and you should be good.

Is the time date thing happening when you plug in to the connectivity kit? Or is it some other time?

Thank you so much. Now I can use my new calculator in my midterm. It just randomly lost all calendar information. I don't really know what happened.
