Diurnal variation in suicide timing by age and gender: evidence from Japan across 41 years

A large number of studies have accumulated evidence for the existence of cyclical changes in the frequency of suicide across time. Many scholars have examined seasonality in suicide, and have shown that its frequency typically increases in the spring and early summer months but that this pattern varies across regions, subpopulations, and methods (e.g. Ajdacic-Gross et al., 2010; Altamura et al., 1999; Chew and McCleary, 1995). The days of the week have also been shown to generate a cyclical change: suicide tends to be more frequent on Mondays or the first workday of the week, and conversely is less likely to occur on weekends (Maldonado and Kraus, 1991; Massing and Angermeyer, 1985; Nishi et al., 2000; Zonda et al., 2009).
