Calculates which day of the week a given date occurred.
Using my own algorithm, this application assigns values to the month, day, and year portion of any date. I made this based on the facts from this site: http://www.searchforancestors.com/utility/dayofweek.html
All dates entered must match this format: mm/dd/yyyy Errors will be prompted for all invalid input values.
**This tool only works for any date after the year 1600 due to implemention of the Gregorian calender.
EDIT: The DayOfWeek default libraries are over-rated, but if you want to simplify this project to one line:
Console.WriteLine(DateTime.Parse(Console.ReadLine()).DayOfWeek);
