The Antediluvian Calendar, a complex timekeeping system from the era before the Great Flood, intricately weaves together various cycles and ages, including the 260-day Tzolken sacred years and the 360-day Tun years. These cycles are reflected in the genealogies of the early patriarchs listed in Genesis 5, with Enos, the third patriarch, marking a significant quarter division in the 360-year Tun cycle with his 90 Tzolken sacred years. This article delves into the mathematical and symbolic significance of these ancient calendar systems, exploring how they shaped the understanding of time in the context of biblical genealogies.

Understanding the Antediluvian Calendar

The Antediluvian Calendar is a testament to the sophisticated timekeeping of ancient civilizations. It incorporates two distinct cycles: the 260-day Tzolken sacred year and the 360-day Tun year. These cycles are not only central to the Mayan calendar but also resonate with the ages of the patriarchs from Adam to Enoch as described in Genesis 5. For instance,Deciphering the Antediluvian Calendar: The 90-Year Age of Enos Articles Genesis 5:9 states, "And Enos lived ninety years, and begat Cainan," highlighting the importance of these time partitions.

The Dual Cycles of the Antediluvian Calendar

The Antediluvian Calendar operates on a dual cycle system:

  • The 260-day Tzolken sacred year, which is followed by a 100-day period leading into the 360-day Tun year.
  • The 365-day solar year, which is divided into four 91-day quarters marked by the four principal Royal Stars, with a final day reserved for numerical matching of days with years.

Each patriarch's primary age is recorded at the time of the next character's birth, creating a cascading sequence of ages that align with these cycles.

The Solar and Lunar Aspects of the Calendar

The 365-year solar cycle is similarly divided, with a 260-year Tzolken sacred cycle followed by a 100-year period leading into the 360-year Tun cycle. The last five years of the solar cycle are split into four-year and single-year elements, emphasizing the theme of numerical matching of days with years.

Adam's primary age of 130 Tun years, for example, halves the 260-year Tzolken sacred cycle, while Seth's primary age of 105 years completes the 365-year solar cycle (Genesis 5:3, 5:6). This pairing of Adam and Seth spans four Mayan 400-year Baktun cycles, covering over 1,600 l/s-years in the secondary age category.

The Significance of Enos's Age

The primary 90-Tzolken-sacred-year age of Enos is particularly noteworthy. It represents one-quarter of the 360-year Tun cycle and is equivalent to 65 Tun years when converted. This quarter division is a recurring theme in the calendar, with the 260-day Tzolken sacred year divided into four quarters by the Mayan Year Bearer days.

The Mathematical Framework of the Antediluvian Calendar

The Antediluvian Calendar's mathematical structure is revealed through a series of equations that demonstrate the interplay between the Tzolken sacred years and the Tun years. For instance:

  • Equation 1: The 260-year Tzolken sacred cycle multiplied by the 360-day Tun years equals 93,600 days.
  • Equation 2: Adam's primary age of 130 Tun years equals 46,800 days, half of the Tzolken sacred cycle.
  • Equation 3: A 360-year Tun cycle multiplied by the 260-day Tzolken sacred years also equals 93,600 days.
  • Equation 4: Adam's primary age converted to Tzolken sacred years equals 46,800 days.

These equations highlight the symmetry and precision of the ancient calendar system, with Enos's age serving as a key marker in the progression of time.

Cultural and Religious Implications

The Antediluvian Calendar is deeply rooted in the religious and cultural practices of ancient civilizations. The 360-day Tun year, for example, is associated with the earliest forms of lunar reckoning and the division of the circle into 360 degrees. This calendar system influenced a wide range of religious, mathematical, and scientific endeavors, including the celebration of the 360-day year in various cultures.

The Egyptian Coptic calendar, which evolved to include a leap day every four years during the reign of King Djoser (circa 2670 B.C.E.), is a modern descendant of these ancient timekeeping practices. Today, the Coptic and Ethiopic calendars continue to follow the Gregorian leap day additions.


The Antediluvian Calendar, with its intricate cycles and ages, offers a fascinating glimpse into the ancient understanding of time. The primary 90-year age of Enos, as recorded in Genesis 5:9, is a testament to the calendar's complexity and its influence on biblical genealogies. For those interested in the study of the Holy Bible and ancient calendars, the Ages of Adam ministry provides valuable insights into these early timekeeping systems.

The Moon has been a celestial guide for humanity, serving as the earliest calendar long before the advent of modern timekeeping. Ancient civilizations across the globe, from the Jewish to the Mesoamerican and the Egyptian, relied on the lunar cycle to structure their lives and understand the passage of time. The changing phases of the moon not only inspired the seven-day week but also played a crucial role in the development of lunar/solar calendars, which were essential for marking longer time cycles. This article delves into the historical significance of the moon as a calendar, its impact on early biblical records, and the intricate systems of timekeeping that have evolved from observing the lunar cycle.
