I had a hard time googling for the Mass sched at Caleruega so I thought of posting it on my blog.
Caleruega’s Sunday Mass is at 11AM. And if you’re planning to visit the place, Caleruega closes at 5:30pm.
Hope I was able to help! :)
NOTE: The sched may change without prior notice

Although I don’t know if they hold Masses here.
