Opera Mystery Day...something

Hey. Does anyone know which day we are up to in the Opera Mystery? If you do please tell me in the comments for this post. :)



Today's gift were a pair of red boots which I personally like. What do you think of them?
Today's letter was the letter h which makes the code...

4 keys reveal the opera ch _ _ _ _ _.
Does anyone have any ideas about what the code is??
