Date Arithmetic (CALC)
The CALC menu performs date arithmetic:
 Determines the day of the week for any date.
 Determines the number of days between dates using one of three
calendars—actual, 365-day, or 360-day.
 Adds or subtracts days from a date to determine a new date.
The calendar for date arithmetic runs from October 15, 1582 to
December 31, 9999.
To display the CALC menu, press , then .
