## Solution 11227: Calculating the Number of Days Between Two Specific Dates Using the BA II PLUS™ or the BA II PLUS™ PROFESSIONAL.

### How do I calculate the number of days between two specific dates using the BA II PLUS or the BA II PLUS PROFESSIONAL?

The example below will demonstrate how to calculate the number of days between two specific dates using the BA II PLUS or the BA II PLUS PROFESSIONAL.

Example: A loan is made on January 1, 2002, but the first payment is deferred until March 30, 2002. How many days does the loan accrue interest before the first payment?

1) Select the date worksheet by pressing [2nd] [1].
2) Press [2nd] [CE/C] to clear out all previous entries.
3) Enter the first date as follows: 01.0102
4) Press [ENTER]. Press the down arrow key.
5) Input the second date as: 03.3002
6) Press [ENTER].
7) Press the down arrow key twice, then [2nd] [ENTER] to toggle between the choices of either actual/actual day-count or 30/360 day-count method. When 'ACT' is in the display (for the actual/actual day-count method), press the up arrow key.
8) Press [CPT] to compute the days between dates.

The loan will accrue interest for 88 days before the first payment.

Please Note: Only dates within the range January 1, 1950 through December 31, 2049 can be used when computing days between two dates.
