So far I have:

clc,clear
day=input('Enter date of the month '); 
if any(day==[3 10 17 24]) 
    dayName = 'Monday' ;
elseif any(day==[4 11 18 25])
    dayName = 'Tuesday' ;
elseif any(day==[5 12 19 26])
    dayName = 'Wednesday' ;
elseif any(day==[6 13 20 27])
    dayName = 'Thursday' ;
elseif any(day==[7 14 21 28])
    dayName = 'Friday' ;
elseif any(day==[1 8 15 22 29])
    dayName = 'Saturday';
elseif any(day==[2 9 16 23 30])
    dayName = 'Sunday';
end
disp(dayName)

However, I am unable to get multiple values to work at once. Any help would be greatly appreciated!

Close, but use a switch statement instead of an if. And use sscanf to get the numbers into a numerical array and use a for loop to process each of the numbers in the list:

clc;
clear;
userInput = input('Enter date of the month (separated by spaces) ', 's')
days = sscanf(userInput, '%f')
for k = 1 : length(days)
  switch days(k)
    case {3, 10, 17, 24}
      dayName = 'Monday' ;
    case {4, 11, 18, 25}
      dayName = 'Tuesday' ;
    case {5, 12, 19, 26}
      dayName = 'Wednesday' ;
    case {6, 13, 20, 27}
      dayName = 'Thursday' ;
    case {7, 14, 21, 28}
      dayName = 'Friday' ;
    case {1, 8, 15, 22, 29}
      dayName = 'Saturday';
    case {2, 9, 16, 23, 30}
      dayName = 'Sunday';
    otherwise
      dayName = 'Unknown';
  end
  fprintf('The day of the week for #%d is %s.\n', days(k), dayName);
end
