Weather and timing

The season and the day of the week (although many nations hold all their elections on the same weekday) can also affect turnout. Weekend and summer elections find more of the population on holiday or uninterested in politics, and have lower turnouts. When nations set fixed election dates, these are usually midweek during the spring or autumn to maximize turnout. Variations in turnout between elections tend to be insignificant. It is extremely rare for factors such as competitiveness, weather, and time of year to cause an increase or decrease in turnout of more than five percentage points, far smaller than the differences between groups within society, and far smaller than turnout differentials between nations.
