Answer 1

clc;
clear all;
str_week = {'Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday'};
str_date = input('Please input a date(mm/dd/yyyy):','s');
str_yearFirst = ['01/01',str_date((length(str_date)-4):(length(str_date)))];
str_datenum = int2str(datenum(str_date,'mm/dd/yyyy')-datenum(str_yearFirst,'mm/dd/yyyy')+1);
disp(['the date ',str_date,' is the ',str_datenum,' day of the year and falls on a ',str_week{weekday(str_date,'mm/dd/yyyy')},'.']);

% Please input a date(mm/dd/yyyy):5/31/2000
% the date 5/31/2000 is the 152 day of the year and falls on a Wednesday.
