How can I create a function that converts the number of a month to the name of a month?

So far I have this.
curdateTime = clock;
Monthnumber=curdateTime(2);
Year=curdateTime(1);
Day=curdateTime(3);
Hour=curdateTime(4);
Minute=curdateTime(5);
Monthname=["January", "Febuary", "March", "April","May", "June", "July", "August", "September", "October", "November", "December"];
Month=Monthname(Monthnumber);
if Hour < 12
fprintf('Good morning, the time is %d minutes past %d o clock AM on %d %d %d.', Minute,Hour,Day,Month,Year)
else
hour=Hour-12;
fprintf ('Good afternoon, the time is %d minutes past %d o clock PM on %d %d %d.', Minute,hour,Day,Month,Year)
end
It gives me an error saying this
Good afternoon, the time is 47 minutes past 8 o clock PM on 22 Error using fprintf
Unable to convert 'string' value to 'int64'.
Error in Jamiesonlab3 (line 15)
fprintf ('Good afternoon, the time is %d minutes past %d o clock PM on %d %d %d.',
Minute,hour,Day,Month,Year)
Any help would be appreciated.

No need to create a function for that.
Monthnumber = 4;
M = month(datetime(1, Monthnumber, 1), 'Name') % also try 'shortname'
% M =
% 1×1 cell array
% {'April'}
To apply that to fprintf,
fprintf('The month is %s\n',M{1})
% The month is April

This question has been solved. I simply had to replace a %d where Month was located in the fprintf with %s. If I do that, the function works fine.
