8. Day/Date Calculations
You can calculate the number of days between two dates, or you can determine what date
comes a specific number of days before or after another date.
Press 2(DAYS) from the Financial 2 screen to display the
following input screen for day/date calculation.
6( g) 2(DAYS)
d1 .......... date 1
d2 .......... date 2
D .......... number of days
To input a date, first highlight d1 or d2. Pressing a number
key to input the month causes an input screen like the one
shown nearby to appear on the display.
Input the month, day, and year, pressing w after each.
After configuring the parameters, use one of the function menus noted below to perform the
corresponding calculation.
• { PRD } … {number of days from d1 to d2 (d2 – d1)}
• { d1+D } … {d1 plus a number of days (d1 + D)}
• { d1–D } … {d1 minus a number of days (d1 – D)}
• An error occurs if parameters are not configured correctly.
Use the following function menu to maneuver between calculation result screens.
• { REPEAT } … {parameter input screen}
• The Setup screen can be used to specify either a 365-day or 360-day year for financial
calculations. Day/date calculations are also performed in accordance with the current setting
for number of days in the year, but the following calculations cannot be performed when the
360-day year is set. Attempting to do so causes an error.
(Date) + (Number of Days)
(Date) – (Number of Days)
• The allowable calculation range is January 1, 1901 to December 31, 2099.
