Holidays and Calendars – Discerning the Times and Seasons

Across civilizations, calendars and holidays develop as structured ways of organizing communal time. In many ancient societies, the cycles of the sun, moon, and stars were used to mark seasons, agricultural rhythms, worship festivals, and civic remembrance. Within a biblical framework, Genesis 1:14 presents the heavenly lights as serving “signs” and markers for seasons, days, and years—language that connects timekeeping with order, meaning, and accountability before God.

As cultures formed distinct identities, special events—religious, historical, or national—were often preserved through recurring holidays. Because holidays can carry layered meanings (theological, cultural, political, and commercial), worldview comparison asks not only what is celebrated but why, and how those celebrations shape beliefs about reality, morality, and human purpose.

Notable Calendar Systems

Calendar systems are formal methods of organizing time, typically anchored in astronomical observation (solar, lunar, or lunisolar cycles) and shaped by cultural priorities such as agriculture, worship, and governance. Because calendars regulate communal life—work rhythms, festival schedules, and historical memory—they often reflect deeper worldview assumptions about order, authority, and sacred time.

1. Gregorian Calendar (solar): The most widely used civil calendar today, introduced in 1582 as a refinement of the Julian calendar to better align the calendar year with the solar year.
2. Islamic (Hijri) Calendar (lunar): A lunar calendar of 12 months used to determine major Islamic observances; because it is not synchronized to the solar year, its months shift through the seasons.
3. Chinese Calendar (lunisolar): A lunisolar system used historically and culturally to determine traditional festivals and seasonal markers.
4. Hebrew Calendar (lunisolar): A lunisolar system used to determine Jewish festivals and sacred times, balancing lunar months with periodic adjustments to maintain seasonal alignment.
5. Hindu Calendars (lunisolar/regional): Multiple regional calendrical traditions used to determine festival cycles and religious observances, often combining lunar months with solar seasonal reckoning.

Holidays Around the World

Every culture maintains commemorations that express identity, memory, and meaning—whether religious, civic, seasonal, or family-based. Some holidays emerge from ancient religious traditions; others arise from historical events, migration, national formation, or community customs. Over time, holidays can change as societies reinterpret older practices, adopt new symbols, or reshape observances in response to cultural and political shifts.

A few notable Holidays are as follows:

1. Christmas: Celebrated on December 25th, Christmas is a Christian holiday commemorating the birth of Jesus Christ. While the exact date of Jesus’ birth is unknown, the December 25 observance became widely established in late antiquity, and scholars discuss multiple historical factors that may have influenced its adoption, including the idea that in the 4th century to coincide with existing pagan celebrations of the winter solstice, providing a Christian alternative.
2. Thanksgiving: Primarily celebrated in the United States and Canada, Thanksgiving is a holiday of gratitude and appreciation. It originated as a harvest festival in North America and has historical roots in English traditions and the Pilgrims’ arrival in Plymouth in 1620.
3. Eid al-Fitr: This is an important Islamic holiday marking the end of Ramadan, the holy month of fasting. It is a time of celebration, gratitude, and giving. The date of Eid al-Fitr is determined by the sighting of the new moon, following the Islamic lunar calendar.
4. Diwali: Also known as Deepavali, Diwali is a significant Hindu festival celebrated in autumn. It signifies the victory of light over darkness and good over evil. The festival lasts five days, and the exact date is based on the Hindu lunar calendar.
5. Hanukkah: Hanukkah, also known as the Festival of Lights, is an eight-day celebration that usually falls in December. It commemorates the rededication of the Second Temple in Jerusalem during the Maccabean revolt against the Seleucid Empire in the 2nd century BCE. The story of Hanukkah is documented in the books of the Maccabees and Talmud. The lighting of the menorah, playing with dreidels (spinning tops), and eating fried foods are traditional customs during this holiday.
6. Chinese New Year: Also known as the Spring Festival, Chinese New Year is a major holiday in many East Asian countries. It marks the beginning of the lunar new year and is associated with various customs and traditions to bring good luck and fortune in the coming year.

Christian & Jewish Holidays

In the history of the Western church, some Christian observances developed alongside (and sometimes in dialogue with) pre-existing cultural festivals as Christianity spread through the Roman world. As a result, certain holidays came to carry both theological meaning and local customs, and Christian communities have evaluated these traditions in different ways across time.

The Bible clearly teaches that feast days and sabbaths functioned as a “shadow of things to come” (Colossians 2:16–17). In the Old Testament context, these appointed times pointed forward to God’s redemptive purposes and to the coming Messiah and His kingdom.

“Therefore let no one judge you by what you eat or drink, or with regard to a feast, a New Moon, or a Sabbath. 17. These are a shadow of the things to come, but the body that casts it belongs to Christ. 18. Do not let anyone who delights in false humility and the worship of angels disqualify you with speculation about what he has seen.”

– Colossians 2.16 – 18 a

This passage shows that believers are not justified by calendar observance or judged spiritually by participation in (or abstaining from) feast days. However, this does not mean that biblical festivals have no value. Studying them helps clarify their historical setting, theological meaning, and how the patterns and symbols of Israel’s worship point to Christ.

This is why the early church celebrated the Jewish Holidays, not only because most of the members of the first church where Jewish, but because these celebrations still had significant meaning. Jesus and His disciples celebrated the Jewish feasts, i.e. the Passover, Feast of Unleavened Bread (Luke 22.7-8).

To this day, we still find value in Christians knowing about and celebrating Jewish Holidays, to learn about their traditional historic meaning and how the Jewish people in the Old Testament celebrated Gods miracles, and how the celebrations point to the Messiah!
