Κυριακὴ πρώτη τοῦ Λουκᾶ to κυριακὴ δωδεκάτη τοῦ Λουκᾶ, also called the Sunday of the Holy Patriarchs (τῶν προπατόρων).
Κυριακὴ πρὸ τὴς Χριστοῦ γεννήσεως: the Sunday before Christmas, also called the Sunday of all the Holy Fathers.
Ἡ τοῦ Χριστοῦ γέννησις: Christmas.
Κυριακὴ μετὰ τὴν Χριστοῦ γέννησιν: Sunday after Christmas.
Ἡ τοῦ κυρίου περιτομή: the Circumcision.
Κυριακὴ πρὸ τῶν φώτων: the Sunday of Lights. See above, [page 168]. The Sunday before Epiphany. Among the Latins a dominica vacans.
The remaining four Sundays of the Greek ecclesiastical year serve to fill up the inequality due to Easter falling earlier or later, in the same manner as in the Latin rite. One, two, or all four of them, as occasion requires, are inserted after Epiphany. They are the Sundays (1) κυριακὴ μετὰ τὰ φῶτα, the first after Epiphany, which is pressed into use when Easter falls in March; (2) the twelfth Sunday after St Luke; (3) the fifteenth after St Luke (the two Sundays in the Christmas season are reckoned as the thirteenth and fourteenth after St Luke since their gospels are taken from that evangelist); (4) the seventeenth Sunday after St Matthew. All four are required when Easter falls on the 22-25 April. In this way the gaps between the end of the old ecclesiastical year and the beginning of the new are filled up.
As far as the immovable feasts are concerned, the Greeks divide all feasts, both movable and immovable, into four classes. The first and highest class contains: Christmas, Epiphany (6th January), Candlemas (2nd February, ὑπαπάντη τοῦ κυρίου ἡμῶν), the Annunciation (ὁ εύαγγελισμός), Easter, Palm Sunday, the Ascension, Pentecost, the Transfiguration, the Assumption (ἡ κοίμησις, 15th August), our Lady’s Nativity (8th September), the Exaltation of the Holy Cross (14th September), and the Presentatio B.M.V. (21st November).
Somewhat lower in rank are the Circumcisio, Nativitas S. Joannis Bapt. (24th June), SS. Peter and Paul (29th June), and the Decollatio S. Joannis Bapt. (29th August). It is not necessary here to enumerate the remaining feasts.
