Back in time?

The janitor cleans the chalkboard on Friday afternoons. Every Monday morning I write the entire new date (May 7, 2007, etc.) on the board. Every other day of the week, I just erase the number (7) and write the new one. This morning, I write the date on my chalkboard, as I do every Monday morning. An hour later a student raises his hand and points to the board. "Ms. Ross?" Nick says "The board says May 14, 2005."

Where my mind was, I cannot say. But this I know for sure. There are only 8 days left!
