Lex calculated the amount of time left before his Heaven and Hell matured. Well, until Heaven matured - the Hell would have to be forcefully matured by then, but that was a concern for slightly later in the day.
It would be a grand occasion because, well, it would give him the opportunity to sit in Heaven, relax, and remember all the times he did bad things.
No wait… Lex accidentally let the Jack side of his personality slip out. It would be a grand occasion because it was one step forward in making his realm as amazing as can be, and allowing him to accept more and more guests who were limited by the available environments within the Inn.
For example, the Seraphim who saw fit to condemn him couldn't really visit the Inn because they could only live inside Heavens.
Anyway, that was good enough of an excuse. First, he created the event with the deadline, and broke the event into two parts. The lead up to the actual event was the first part of the event.
