What time is the practice tomorrow? What time is tomorrow's practice? ( no 'the')

The first one is a bit more natural without the 'the', but it makes sense either way. The second shouldn't have a 'the' at all though. "What time is (the) practice tomorrow?" "What time is tomorrow's practice?" Also, the title should say 'sentences' as a plural. Normally it should be have an 'are' as well, but sentence fragments aren't uncommon in titles. Hope that helped.
