Any idea how how hexadecimal got to be a description of that system?

Wikipedia says that it is a combination of hexa- from six in Greek and decimal from ten in Latin from the 1950s. Various terms such as senidenary and sexadecimal have also been used.

And 2) I don’t have an answer for 10/31 vs 12/25??

Because Oct 31 = Dec 25 (octal 31=decimal 25).
