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.
