Introduction

Welcome to the Zadok Biblical Calendar—a unique approach to timekeeping that integrates scriptural principles, Dead Sea Scrolls data, and astronomical observations. This calendar is anchored in a 364‐day year , arranged in 6‐year cycles with a 7‐day leap afterward, and 24‐priest rotations from 1 Chronicles 24.

I do not claim to be an expert or to have all the answers, but I'm sharing my journey studying the Scriptures and ancient texts. By adopting this framework that never drifts—this calendar offers a fresh lens through which to align modern life with biblical rhythms and the celestial design. I invite you to explore how each day matches with priestly courses, and nestled into a 364‐day year that remains in sync with creation.

The Zadok Biblical Calendar relies on Torah, Prophets, New Testament, Enoch, Jubilees, and the Dead Sea Scrolls (notably the accounts of the Sons of Zadok, descendants of Aaron). It aims to recapture a holy timekeeping system that is both ancient and profoundly relevant today.

The Concept of the Zadok Biblical Calendar

364 Days, 6‐Year Blocks, and a Leap Week

At its core, this calendar keeps each year at exactly 364 days (52 weeks). After 6 such years, we insert a 7‐day “silent” leap to realign with the solar cycle. This results in a 2,191‐day cycle (2,184 days of counted time plus 7 days of leap), ensuring we never drift out of season.

The 24 Priestly Courses

The Dead Sea Scrolls and 1 Chronicles 24 describe 24 orders of priests, each serving 7 days in a perpetual rotation. This calendar assigns a specific priestly course to each date. If a leap week cuts across the end of a 6‐year block, the priest simply resumes service after the leap. This provides a tangible link to the Temple era and priestly service cycles.

March 20, 2019, as a Modern Epoch

We anchor the present calendar on March 20, 2019, marking it as the epoch for Year 1. This specific date was identified and analyzed by researchers at Gospel Worth Dying For , who demonstrated that it aligns perfectly with the 364-day cycles, priestly courses, and the solar equinox timing. From that point onward, each 364-day year proceeds in a straightforward manner, with a 7-day “silent” leap week added after the 6th year ends, ensuring stable alignment with the solar year.

In essence, March 20, 2019, became a modern “reset point” for this Zadok system—coinciding with both scriptural patterns and observable celestial markers. By starting from this epoch, the calendar stays in step with the vernal equinox while preserving the 6-year sabbatical rhythm and daily priestly service.

Key Differences from the Gregorian Calendar

• Fixed 364 Days: Each year has exactly 364 days, divided neatly into 12 months (four months have 31 days, the rest 30). After 6 years, a 7‐day leap is inserted. This ensures no long‐term drift.
• Priestly Course Rotation: Instead of ignoring the Temple’s priestly system, this calendar integrates a daily assignment of the 24 courses, giving you a living connection to the biblical service cycle.
• Seamless Season Alignment: By adding a 7‐day leap after every 6 years, the calendar stays near the spring equinox, preserving the scriptural requirement for Passover and other feasts to remain in their appointed seasons.

Through these principles, the Zadok Calendar endeavors to restore a timekeeping system believed to be used by the Sons of Zadok and reflected in the Dead Sea Scrolls—unifying solar cycles, lunar signs, and priestly service into a single, coherent framework.

How to Use the Zadok Biblical Calendar

1. Identify the Year: When you visit the calendar page, you can select or search for a specific year. The calendar then displays 12 months, each with 30 or 31 days (depending on the quarter of the year).
2. Check Daily Priest: Each date cell shows a Gregorian date, the day number (1–364), the priestly course currently serving. If it’s a feast day or Sabbath, you’ll see a colored bar at the bottom of the date cell.
3. Observe the 6‐Year Cycle: Every year is 364 days until the 6th year finishes. Then a 7‐day “silent” period is inserted before the next cycle. You won’t see those leap days assigned to any date or priest; the current priest simply resumes service after the leap.
4. Plan Feasts & Holy Days: The calendar indicates scriptural festivals at their rightful season. You can use the built‐in alignment to see exactly when Passover, Unleavened Bread, Shavuot, etc., occur relative to the Gregorian dates, and the priestly rotation.
5. Enrich Your Study: By correlating daily readings or biblical events with the priest on duty, you can deepen your connection to ancient Temple practice and the “heavenly luminaries” God appointed for signs and seasons.

Through these steps, the Zadok Biblical Calendar becomes a practical tool for both everyday scheduling and spiritual reflection. It helps you live in sync with a biblical worldview that merges creation’s rhythms, scriptural mandates, and the legacy of the Temple priests.

Last Words

We hope this updated approach clarifies the essence of the Zadok Biblical Calendar. By combining a 6‐year cycle (364 days each year + 7‐day leap), and a 24‐priest rotation, we believe this system may echo the very timekeeping used by the Sons of Zadok and described in Scripture. May it deepen your connection to the divine order and the rhythms of creation.
