If Mohammed Can't Come to Friday, Friday will Come to Mohammed

Daniel announced a few minutes ago that he's going to have a concert, but apparently it's a Fridays-only concert. A few minutes later, he announced, with a smile:

"Daddy, it's Friday."

Me: No, actually it's Saturday.

Daniel: It's Pretend-Friday, so we're gonna have the concert.
