So late this week if all goes well, next week if some minor problems and week after if Murphy's Law holds.
Law of Reversed Outcomes: the summoning of a Law as an attempt to predict an outcome will cause it not to happen, to disprove and ridicule the summoner.
Corollary: If the summoner is aware of the Law of Reversed Outcomes and summons a law (such as Murphy's) intentionally as an attempt to make it not happen, it will happen anyways.
