Objective To compare weekday and weekend suicide frequency in Colombia using Binomial and Poisson distributions to evaluate the weekend effect. Method A cross-sectional study was conducted using public administrative records of completed suicides (CSs) from 2015 to 2023, analyzing personal, temporal, and geographic variables. The frequency of CSs on weekdays and weekends was measured by comparing proportions and daily rates using Binomial (π, 95% CI) and Poisson (λ, 95% CI) distribution models.
