. Courtney was trying her hardest to keep up during choir rehearsal, but she was
just not prepared. The choir director pulled her aside and asked her if she had
been practicing her songs. Courtney said, "Yes, of course I've been practicing. My
brother came home from college on June 29th to help me out, and then! spent
all day June 30th and June 31st practicing on my own in my room." The director
immediately knew Courtney was lying about the amount of time she spent
practicing. How did he know this?

The choir director knew this because June 31st doesn't exist.
