Does that make sense? So the title or name of the event is not mistaken for another, but instead I believe the date or the event itself can be misinterpreted. Since, in order to know exactly what happened, you need to be there, and at the same time, there are many different perspectives. If you need further explanation, just let me know.

A revel is a wild celebration. Your context clue here is the detail that it went "whirlingly on". This gives the image that things are spinning and it is something that could end at midnight. An party hat doesn't end at midnight. A type of dance is something that can spin, but it usually doesn't continue on until midnight. A specific dance type usually only last for a few minutes. An appearance does not make sense.
