How do I display numbers enclosed in single quotes from DICOMINFO?

So, I obtained the DICOM information of a particular file using the dicominfo function. However, when I want to access the Date of the exam and display it, I'm getting an error as it's enclosed in single quotes.

info1 = dicominfo(filename1);
fileID = fopen('xxx.txt','w'); 
fprintf(fileID,'The date is %d   \n      ',info1.DateOfLastCalibration);

The output im getting is,

The date is 50   
The date is 48   
The date is 49   
The date is 50   
The date is 49   
The date is 50   
The date is 49   
The date is 55

This is what's given in the DICOM file info: DateOfLastDetectorCalibration: '20121217'

The output I want is:

The date is 20121217

Can you guys help me out?

fprintf(fileID,'The date is %s \n ',info1.DateOfLastCalibration);

FYI

>> double('20121217')

ans =

      50    48    49    50    49    50    49    55
