HOW TO PLAY DBD



This program, DBD, calculates the days between dates. The program prompts

you for two dates.  After each date it displays the day of the week for that

date. After the second date the number of days between the two dates is

displayed. The number of days between dates is calculated such that there are

365 days between 1/1/93 and 1/1/94. The algorithm logic recognizes that the 

year 1900 was not a leap year and that the year 2000 is a leap year. This is

because leap years are defined to be those years that are divisible by four 

unless they are divisible by one hundred unless they are also divisible by 

four hundred.
