The Nativity Fast
Sunday 15 November – Thursday 24 December 2026
The Nativity Fast is the Church's forty-day preparation for Christmas: from 15 November to 24 December inclusive. It is often called Saint Philip's Fast, because it begins on the day after that apostle's feast. Where Western Advent lasts about four weeks, the Orthodox fast keeps the full forty days — a winter counterpart to Great Lent, though kept far more gently, leading not to the Cross but to the cave of Bethlehem and the mystery of God become a child.
At a glance
- •15 November to 24 December — forty days before the Nativity of Christ
- •No meat, dairy or eggs throughout; fish, wine and oil on many days early in the fast
- •Stricter from 20 December: no fish in the final days
- •Paramony (24 December): strict fast until evening
- •Followed by fast-free days until the Eve of Theophany
The discipline begins mildly. Meat, dairy and eggs are set aside throughout, but for most of the fast fish, wine and oil are permitted on many days — Saturdays, Sundays and the feasts that stud the season, among them the Entry of the Theotokos into the Temple (21 November) and Saint Nicholas (6 December). From 20 December the fast tightens: fish is no longer eaten, and the rule approaches that of Lent as the feast draws near. The final day, the Eve of the Nativity or Paramony (24 December), is kept as a strict fast, traditionally with no food until the evening star recalls the star of Bethlehem — or, in parish practice, until after the evening Liturgy.
The fast's forty days carry the Church through the darkest weeks of the year with a steadily brightening expectation. The Sundays before the Nativity remember the Forefathers and the whole genealogy of Christ, and the hymns of the season begin to sing of the coming feast weeks in advance — "Christ is born, glorify Him" is first heard long before 25 December. When the feast arrives, it opens into a fast-free period lasting until the Eve of Theophany.
For a newcomer, this fast is a gentle apprenticeship: its early weeks ask little more than the weekly fast does, and its gradual tightening teaches the shape all fasting has — preparation that deepens as the feast approaches. Amid December's noise, it is also intensely practical: a daily, bodily reminder of what the season is actually for. Agree your own measure with your priest, and keep the last days, especially the Eve, as fully as you can.
Fasting is a guide, not a law: how you keep it is worked out personally, with your parish priest. Illness, age, pregnancy and circumstance all soften the rule, and it is never a measure for judging yourself or others.
