Suicide data from Sweden (1911-1993) and New Zealand (1975-1995) were used to test a hypothesis derived as an extension of the Seasonal Affective Disorder concept. Contrary to the hypothesis, but similar to what Durkheim had reported regarding Central Europe in the nineteenth century, suicides peaked in late spring (May in Sweden, November in New Zealand). Durkheim's hypothesis that there would be more monthly variation in suicides in rural areas was strongly supported. Our hypothesis is that people abandon life when it is least difficult because of a disjuncture between experience and expectation.
