I do agree with you, sir. People at the time does not track 24 hour day. Besides, this verse proves that it was a Friday.

"Then he took it down, wrapped it in linen cloth and placed it in a tomb cut in the rock, one in which no one had yet been laid. It was Preparation Day, and the Sabbath was about to begin."
