The Ides of March
The Ides of March, a prolog which sets up the situation, occurs late in the previous school year in another state. In May, Neil applies for work at Keirnan school. During August he prepares for the coming school year.
Day One is very early September. Now it would be early August. Halloween announces itself, and Christmas occurs during the chapters Evaluation and Discipline.
Terror happens on Martin Luther King Day. That is not a political statement. That is the day in my real world that a school shooting happened in a nearby city. I had made an agreement with myself to match my fictional world with the real one, so this day took me places I would never have gone on my own.
Home happens at Cinco de Mayo (the fifth of May) as the school year is winding down.
I wrote an honest story. Everything that happened, could have happened in my real world. Many of these things were close analogs to things that did happen.
I never faced false accusation, but I was aware every day that I might. That is what it means to be a male teacher in America today.
