Figure 4. Number of people attacked across 5-day intervals of the lunar cycle.

Solid circles: days when the moon was waxing; double circles: days when waning. Yellow area indicates average hours of daylight. Fewer people were attacked between 6:00 and 9:45 PM on the 5^th–14^th days of the lunar cycle (when the moon is increasingly bright and always above the horizon in the evening); most victims were attacked on the 15^th–29^th days (when the moon rises later after sunset each evening).
