Exercise 70

Find the exact number of days from the first date to the second. (See Examples.)
Finding the Number of Days from One Date to Another, Using a Table
Use the table to find the number of days from (a) March 24 to July 22, (b) April 4 to October 10, (c) November 8 to February 17 of the following year, and (d) December 2 to January 17 of the following year. Assume that it is not a leap year.
SOLUTION
(a)

(b)

(c) November 8 is day 312, so there are 365 ? 312 = 53 days from November 8 to the end of the year. Add days until the end of the year plus days into the next year to find the total.

(d) December 2 is day 336, so there are 365 ? 336 = 29 days to the end of the year. Add days until the end of the year plus days into the next year to find the total.

Finding the Number of Days from One Date to Another, Using Actual Days
Find the number of days from (a) June 3 to August 14 and (b) November 4 to February 21.
Quick TIP
To find the number of days from one date to another, do not count the day the loan was made, but do count the day the loan is paid.
SOLUTION
(a) June has 30 days, so there are 30 ? 3 = 27 days from June 3 to the end of June.

(b) November has 30 days, so there are 30 ? 4 = 26 days from November 4 to the end of November.

October 12 to February 22 of the following year
