Alcohol consumption in the population is found to vary through the months of the year, with increased consumption, including sporadic heavy drinking occasions, occurring during holidays, festivals, large sports events, and public holidays – such as Christmas, Easter, St. Patrick’s Day, and the summer holidays.[1] This seasonality in consumption has a harmful, knock-on effect on public health, hospitals and Emergency Departments, crime and violence, drink driving and road traffic collisions, suicide and self-harm, and domestic, sexual, and gender-based violence.
