Solution 34851: Finding Days Between Dates on the TI-84 Plus C Silver Edition.

How can I find the days between dates using the Finance App on TI-84 Plus C Silver Edition?

To calculate the number of days between two dates using the actual-day-count method, use the date function dbd( ) or "days between dates". date1 and date2 can be numbers or lists of numbers within the range of the dates on a standard calendar. The dbd( ) function is found by accessing the Finance App and selecting option D. The syntax is as follows:

dbd(date1,date2)

Please Note: Dates must be between the years 1950 through 2049.

date1 and date2 can be entered in either of the two formats below:

MM.DDYY United States or DDMM.YY Europe.

Example: Find the number of days between 12/20/1988 and 12/20/2006:

1) Press [APPS] [1] [ALPHA] [D].
2) Press [1] [2] [.] [2] [0] [8] [8] [,].
3) Press [1] [2] [.] [2] [0] [0] [6] [)].
