Miracle Monday

Miracle Monday is a novel written by Elliot S. Maggin, starring the DC Comics superhero Superman. It was published in 1981.
The novel introduces the holiday Miracle Monday, which occurs annually on the third Monday of May.
Kristin Wells, a history graduate student from the far future, uses time travel technology to arrive in the present, for the purpose of finding out the origin of the holiday known as Miracle Monday, which is known only to be somehow connected to Superman.
Ultimately, Superman refuses to kill Kristin, even if it means he would have to spend the rest of his life battling Saturn. At that moment, because of the rules that bind demons, Saturn is defeated, and forced to grant Superman a wish. He asks that everything that happened since Saturn’s arrival be undone, and it is granted, with Saturn then being banished back to Hell. However, a lingering memory of the events remained within the souls of humanity, causing them to begin celebrating the day every year, on the third Monday of May, starting the Miracle Monday tradition. Kristin then returns to the future to reveal this fact to the public.
