A feast day (or festival) is the date a saint, a holy event, or a holy object is commemorated in the liturgical life of the Orthodox Church. A feast day is primarily celebrated through the hymnography of the Church's divine services appointed to be celebrated on such day.
The Orthodox Church commemorates certain saints or sacred events in its history every day of the year. The feast day of a saint is generally the date of his or her death.
The feasts of the Orthodox Church, as with the canonization of saints, always comes from the living devotion of the Christian people. Feast days of the Church are not "institutions" which are legislated by some ecclesiastical authority apart from the interest and consent of the people. If there were no popular interest and veneration of a certain holy person, there would be no official canonization and no liturgical festival established in there honor.
However, if a someone is recognized as a saint, the Church hierarchy will set the day of the feast and will compose the proper liturgical service and hymns to be used in the celebration. But the celebration will then depend solely upon the will of the faithful. Once established, the feast could only disappear organically, in a way similar to its appearance. It could not be "disestablished" by the decree of any church authority, only by lack of interest.
