It seems necessary to make dates fit to assume that the named century ends not on the 00s, but on the 88s. 7a twice is a significant number on Discworld, and the last great change of government was in 1688. Carpe Jugulum mentions that the century is ending, and millennial events follow in Thief of Time and Night Watch. These suggest that the University calendar lags ours by twelve years.
