can i have my own holiday if yes can any one help me please?

The weekday function labels Saturday as 7 and Sunday as 1, so to determine a weekend, test for those numbers and label the days appropriately. This code illustrates the concept. Although it is probably more detailed than you need for your code, the complexity is necessary to illustrate the concept:

Next7Days = now + [0:7]';                                           % Date Numbers For Next 7 Days
[DayNumber, DayName] = weekday(Next7Days);                          % Get Day Number & Day Names For Next 7 Days
DayType = repmat({'Weekday'}, size(DayNumber,1), 1);                % Initialise ‘DayType’ Array
DayType((DayNumber == 1) | (DayNumber == 7),:) = {'Weekend'};       % Label Weekends
Next7DaysCell = {DayNumber  DayName  DayType};                      % Collect In Cell Array (Not Necessary Except To Illustrate Here)
for k1 = 1:size(DayNumber,1)                                        % Loop To Print Results
    fprintf(1, '%.0f  %s  %s\n', Next7DaysCell{1}(k1), Next7DaysCell{2}(k1,:), Next7DaysCell{3}{k1})
end

The result is:

7  Sat  Weekend
1  Sun  Weekend
2  Mon  Weekday
3  Tue  Weekday
4  Wed  Weekday
5  Thu  Weekday
6  Fri  Weekday
7  Sat  Weekend
