Major Christian Holidays: Dates, Meanings & Liturgical Rhythm

The Christian liturgical year orbits around two poles: Incarnation (Christmas cycle) and Resurrection (Easter cycle). Here are the major observances, ordered chronologically.

🎄 Advent (Late Nov – Dec 24)

• 4 Sundays before Christmas.
• Theme: Expectation, preparation, "already/not yet."
• Practices: Advent wreath (4 candles), daily readings, calendars.

🎁 Christmas (Dec 25 / Jan 7 Orthodox)

• Nativity of Jesus — Incarnation celebrated.
• Christmastide: 12 days → Epiphany (Jan 6).

✝️ Epiphany / Theophany (Jan 6 / Jan 19 Orthodox)

• West: Magi visit (manifestation to Gentiles).
• East: Jesus' baptism (manifestation as Trinity).

🌿 Lent (40 Days, Variable Feb–Mar)

• Ash Wednesday → Holy Saturday (excl. Sundays).
• Fasting, penitence, almsgiving — preparation for Easter.

🌿 Holy Week (Palm Sunday → Easter)

• Palm Sunday: Triumphal entry.
• Maundy Thursday: Last Supper, foot washing, institution of Eucharist.
• Good Friday: Crucifixion, death — solemn fast, veneration of cross.
• Holy Saturday: Vigil, waiting, Easter fire.

🌅 Easter (Pascha) — Moveable Feast (Mar 22 – Apr 25)

• Resurrection — central feast of Christianity.
• Date: First Sunday after first full moon after vernal equinox (Computus).
• Eastertide: 50 days → Pentecost.

⬆️ Ascension (40 Days Post-Easter)

• Jesus' ascent — Thursday (often transferred to Sunday).

🔥 Pentecost (50 Days Post-Easter)

• Holy Spirit descent — Church's birthday.
• Note: Listed twice in source; single feast.

👑 Assumption / Dormition (Aug 15)

• Catholic/Orthodox: Mary's bodily assumption / falling asleep.
• Protestant: Generally not observed.

🕊 All Saints' Day (Nov 1)

🕯 All Souls' Day (Nov 2)

• Faithful departed — prayers for souls in purgatory (Catholic) / remembrance (Protestant).

👑 Christ the King (Last Sunday before Advent)

• Culmination of liturgical year — cosmic sovereignty.

📅 Key Variables

• Western (Catholic/Protestant) vs. Eastern (Orthodox) calendars: Christmas Dec 25 / Jan 7; Easter often different (Julian vs. Gregorian Paschalion).
• Denominational emphasis: High church (liturgical) vs. low church (selective).

The calendar is theology in time — each feast makes a doctrine livable.
