Suicides in Cuyahoga County, Ohio, for 1972-1975 are tabulated by year, month of year, day of week, lunar phase, & holiday occurrence. Only lunar phase demonstrates a significant (p<.01) variation in suicide rate; an increase is observed in this sample with respect to new moon phase but not for full moon phase. Explanations for this finding are considered, but the precise reasons remain unknown.
