This is a chronology of the artist Vincent van Gogh . It is based as far as possible on Van Gogh's correspondence.  However, it has only been possible to construct the chronology by drawing on additional sources. Most of his letters are not dated, and it was only in 1973 that a sufficient dating was established by Jan Hulsker , subsequently revised by Ronald Pickvance and marginally corrected by others. Many other relevant dates in the chronology derive from the biographies of his brother Theo , his uncle and godfather Cent, his friends Émile Bernard and Paul Gauguin , and others.
