ennichi

With the spread of Kanzeon worship among the common people, ennichi (days special to Kannon) were established. Although ennichi are not particular to Kannon, and are established for other hotokes and deities, those for Kannon were the earliest to be established and became the most popular.

Observance of lucky days, or ennichi, began around the 12th century , when Buddhist thought blended in with the common beliefs of the time. Which days are lucky? It depends on the temple or shrine you visit. When ennichi religious services are held, small portable shops line both sides of the road, ready to catch the eye of pilgrims.

Ennichi, the Buddhist equivalent of shrine festivals, provided an opportunity for worshipers to visit temples and pray to the buddhas or bodhisattvas in whom they had placed their faith. The custom of holding ennichi on certain days can be traced back to the late Heian period (794–1185).
