What are the days of the Christian calendar? Introduction The phrase “days of the Christian calendar” refers to specific periods or annual observances that have developed to commemorate key events in biblical history and the life of the Church. While Scripture does not mandate observing all these days as a strict calendar, believers through the centuries have found it beneficial to structure their worship schedule around these events so as to remember and celebrate foundational truths of the faith. The purpose of these commemorations is to focus hearts and minds on God’s redemptive plan, announced in “the Law and the Prophets” (Luke 24:44) and culminating in the life, death, and resurrection of Jesus Christ. Below is an extensive overview of the primary days and seasons found in many Christian calendars. Scripture references are drawn from the Berean Standard Bible, and historical and archaeological evidence is referenced where applicable. 1. The Lord’s Day (Sunday) Believers traditionally gather on Sunday in honor of the resurrection of Christ. According to the Gospels, the resurrection occurred “early on the first day of the week” (Mark 16:2), making Sunday a day of special significance. Early Christians adopted Sunday worship from the start (cf. Acts 20:7, Revelation 1:10). Ancient documents, including writings of the Church Fathers such as Ignatius of Antioch, attest to the practice of meeting on the first day, confirming the scriptural implication that the earliest believers saw Sunday as a celebration of Christ’s victory over death. 2. Advent In many Christian traditions, Advent marks roughly four weeks leading up to Christmas. “Advent” means “coming” and focuses on two key themes: (1) remembering the first coming of Jesus as a child in Bethlehem (Matthew 1:23), and (2) anticipating His future return in glory (Revelation 22:12). Though Advent observances as they are today developed over time, the concept of preparation and expectation draws from numerous scriptural themes of waiting upon the Lord (Psalm 130:5–6). Archaeological evidence of early Christian house churches, such as the third-century Dura-Europos church in Syria, shows that Christians historically used set times to reflect upon scriptural promises, consistent with the principle of structured worship. 3. Christmas (Nativity of Christ) Christmas celebrates the birth of Jesus, typically observed on December 25 in the Western tradition. Though the exact date of Christ’s birth is not stated in Scripture, the event itself is foundational to the Christian faith, as foretold by Isaiah: “Therefore the Lord Himself will give you a sign: Behold, the virgin will conceive and give birth to a son, and will call Him Immanuel” (Isaiah 7:14). The Gospel of Luke describes the birth in detail (Luke 2:1–20). Historically, December 25 was selected in the West by at least the early fourth century, as noted in some Church documents (e.g., the Calendar of 354). While the exact dating method may have varied, the focus of Christmas remains that “the Word became flesh and dwelt among us” (John 1:14), a central theological truth supported by comprehensive manuscript evidence of the New Testament that has survived in thousands of Greek manuscripts and early translations. 4. Epiphany Epiphany, commonly observed on January 6 in many traditions, commemorates the manifestation of Jesus to the Gentiles. The event is often linked with the visit of the Magi (Matthew 2:1–12), showing the universal scope of Christ’s saving mission. Historically, early churches in the East emphasized the baptism of Jesus in the Jordan River (Matthew 3:13–17), also aligning with the theme of Christ’s revelation to humanity. 5. Lent Lent is a period of preparation and reflection before Easter, traditionally lasting about 40 days (excluding Sundays). It recalls the 40 days Jesus spent fasting in the wilderness and resisting temptation (Matthew 4:1–11). The practice of dedicating a time of repentance and self-denial finds biblical support in numerous passages about seeking God wholeheartedly (Joel 2:12–13). Documentation from early Christianity indicates believers often engaged in fasting and prayer before Easter, reflecting a desire to identify with Christ’s sufferings. While the specific structure of Lent has varied across time and place, its underlying purpose has remained the deepening of a believer’s relationship with God. 6. Holy Week Holy Week recounts the final days of Jesus’ earthly ministry, culminating in His crucifixion and resurrection. Each day in Holy Week can hold unique significance: - Palm Sunday. Remembers Christ’s entry into Jerusalem when the crowds cried, “Hosanna!” (Matthew 21:9). Archaeologically, ancient manuscripts like the Codex Alexandrinus and external writings indicate the Church’s longstanding observance of Christ’s triumphant entry. - Maundy Thursday (Holy Thursday). Commemorates the Last Supper (Luke 22:14–20) and Jesus’ demonstration of servanthood by washing His disciples’ feet (John 13:4–17). - Good Friday. Remembers the crucifixion of Jesus (Mark 15). Historical and geological corroborations around Jerusalem, including centuries-old Christian pilgrim sites and the Church of the Holy Sepulchre, align with scriptural references to Jesus’ death and burial. - Holy Saturday. Reflects on Jesus’ body resting in the tomb. This time of solitude and somber reflection reminds believers of the anticipation between the crucifixion and the resurrection (Matthew 27:59–66). 7. Easter (Resurrection Sunday) Easter celebrates the cornerstone of the Christian faith: Jesus Christ’s resurrection from the dead. As Paul summarizes, “If Christ has not been raised, our preaching is worthless, and so is your faith” (1 Corinthians 15:14). The bodily resurrection is central to the gospel message, and extensive historical, textual, and archaeological testimony (including secular references from ancient historians like Tacitus and Josephus) has confirmed the early Church’s unwavering belief in the risen Christ. The timing of Easter historically derived from Passover, as Christ’s death and resurrection occurred during the Jewish Passover season. This link underscores the consistency of Scripture, highlighting how Jesus fulfills the “Lamb of God, who takes away the sin of the world” (John 1:29). 8. Ascension Day Ascension Day, typically observed 40 days after Easter (Acts 1:3), marks Jesus’ ascent into heaven. Luke’s writings report that Christ “was taken up before their eyes, and a cloud hid Him from their sight” (Acts 1:9). This event signifies His exaltation and the promise of His eventual return (Acts 1:11). Early testimonials such as the writings of Eusebius attest to the Church’s recognition of this remarkable moment. 9. Pentecost Pentecost, occurring 50 days after Easter, commemorates the outpouring of the Holy Spirit upon the disciples, fulfilling the promise Jesus made (John 14:16–17). According to Acts 2:1–4, “they were all together in one place” when the Holy Spirit descended, equipping them for global ministry. The day connects directly to the Jewish Feast of Weeks but gains its fuller meaning in the Church as the inauguration of empowered witness to the world. Historically, Pentecost has been recognized since the earliest centuries, reflecting the Church’s conviction regarding the transforming work of the Holy Spirit. This event is attested in manuscripts and supported by the wide geographic spread of the Church in an astonishingly short time after the resurrection—a fact historians consistently note. 10. Other Commemorations Many Christian traditions include other commemorative days, such as: - Trinity Sunday. Reflects on the nature of God as Father, Son, and Holy Spirit (cf. Matthew 28:19). - All Saints’ Day. Honoring believers throughout history who have persevered in the faith (cf. Hebrews 12:1). - Reformation Day (in some Protestant circles). Marks historical events and doctrinal clarifications that have shaped church history. Though these days vary by denomination and historical context, they each center on biblical truths and God’s work in the world. Conclusion The Christian calendar, in its various forms, serves as a tool to direct focus upon key elements of God’s redemptive plan. From weekly gatherings on the Lord’s Day to major annual observances like Easter and Christmas, each commemoration draws believers into deeper reflection on the holistic message of Scripture. Archaeological findings, ancient extra-biblical documents, and consistent manuscript evidence confirm the reliability of the biblical accounts that underpin these sacred days. As a result, the faithful have found these ordered observations to be a meaningful way to fulfill the exhortation in Philippians 4:8 to meditate on all that is “true, noble, right, pure, lovely, admirable,” culminating in worship of the One who is our Creator and Redeemer. |
