Multiply number of days for each month to data column

Hello, I have a 1 x 10 cell which includes 10 tables. In all tables I have the date column and precip column. Dates are in monthly format from 1989 to 2018. I want to multiply the number of each month to the corresponding precip value in the same row. I want also to consider leap years. Here is my try so far:

for i = 1:numel(test)
    t = test{i};
    t.precip = eomday(date)*precip
    test{i} = t;
end

this code gives me an error:

Error using eomday (line 13)
Y must be an integer year number. 

I don't know what to do. Any help is highly appreciated. I attached my file.

Thank you.

Best regards

for i = 1:numel(test)
    test{i}.precip = test{i}.precip.*eomday(year(test{i}.date),month(test{i}.date));
end
