Days between Dates : HP-12C

 How to calculate the days between two dates on the HP-12C calculator.

This is quite straightforward, and the default method of entering a date is mm.ddyyyy so the 19th September 2007 would be 9.192007 and todays date would be 9.202020 so step one would be to key in the first date and press enter to add it to the stack. 

Then key in the second date, press the blue "g" function key and then the EEX key which gives the answer, in this example, 4750 days.
