When was Les Misérables written?

It opens in 1815 in Toulon with Valjean just being released from prison who goes on to break his parole. 8 years later he is the mayor of Montreuil-Sur-Mer. He goes on to rescue a young Cosette from the Thenardiers and the story skips ahead 10 years later, set in Paris with the end of Act 1 ending just before the 1832 student revolution. Act 2 all happens over a short space of time, meaning Les Miserables would end in 1832 or possibly early 1833.
