1. The date doesn’t actually change every year
While the Dragon Boat Festival falls on a different date every year on the Gregorian calendar, the holiday actually occurs on the fifth day of the fifth month every year on the Chinese Lunar New Year calendar. Due to numerous legends and the date’s concurrence with the annual flood period and midsummer, a time when insects and bacteria tend to spread quickly, people considered this day to be a time of misfortune and adopted several customs to ward off bad luck and pray for good fortune.
