The daily feasts of each confession appear in different columns on the calendar.
For example, for Catholics March 25 is the Annunciation of the Lord. For the Orthodox it is the Annunciation of the Mother of God. For the Anglicans, it is the Annunciation of Our Lord to the Blessed Virgin Mary. On that day, the Bose Monastery commemorates monk John of Dalyatha, while the Jews remember their martyrs of the pogroms in Ukraine.
The calendar also includes Buddhist and Muslim feasts. Protestant feasts and memorials are not included, however, since the denominations are not unified.
The calendar was published by Qiqajon, of the Bose community, whose prior is monk and writer Enzo Bianchi.
Bose is a monastic community of men and women of various Christian denominations. In recent years, it has become a focal point of ecumenical dialogue between Christians, especially Orthodox and Catholics.
