"The observance of holy days occupies a central place in every religion. Through their commemoration, the calendar year becomes the stage on which the signal events associated with the life and ministry of the divine Manifestations of God are annually remembered and honoured. This remembrance has both a personal dimension, providing a time for reflection on the significance of these events, and a social dimension, helping to deepen the identity and foster the cohesion of the community." - Preface
