Do after-school programs count for Child and Dependent Care Expenses?

Hi there,
I just wonder whether after-school programs such as piano lessons, volleyball, ballet, tennis and so on count for Child and Dependent Care Expenses. Because I sometimes work in the weekend and send my kid to one of those programs, so do these programs have to happen on weekdays after school or weekends are okay too? Do we have to provide the SSN/EIN of the care provider to file the expenses?
Thank you very much.
