Enoch Calendar
📜 The Foundational Question
Wednesday or Thursday?
Seven independent biblical anchors — including the Book of Enoch itself — spanning fifteen centuries of history, settle which day starts the Enoch year — the one question every other date on this calendar depends on.
Read the seven-anchor argument
Known by many names

The 364-day solar calendar documented in 1 Enoch 72 — the original calendar of the Bible — has been kept, copied, and studied under many names across more than two thousand years of history. Those names cluster into two distinct traditions — sharing the same 364-day structure but differing by exactly one day in where the year begins.

The Wednesday Tradition

Year begins on Wednesday — the tradition recorded in the Dead Sea Scrolls after the Babylonian exile. Known as:

  • Dead Sea Scrolls calendar
  • Qumran calendar
  • Essene calendar
  • Jubilees calendar
  • Book of Jubilees calendar
  • Priestly calendar
  • Sectarian calendar
  • Zadokite calendar
The Original Enoch Calendar

Year begins on Thursday — drawn directly from 1 Enoch 72 and confirmed by seven independent biblical anchors. Known as:

  • Bible calendar
  • Biblical calendar
  • Calendar of the Bible
  • Enoch calendar
  • Book of Enoch calendar
  • 1 Enoch calendar

The two traditions differ by a single day — a drift acquired during the Babylonian exile and confirmed by seven biblical anchors spanning fifteen centuries of history. Read the full argument →

About the Calendar

An ancient order,
made accessible

The 364-day solar calendar was first revealed to Enoch by the angel Uriel, who guided him through the heavens and showed him the laws governing the luminaries, their seasons, and their appointed times — written on the heavenly tablets and recorded in 1 Enoch 72. Preserved among the Dead Sea Scrolls by the Essene community at Qumran, it is a system of worship, festivals, and appointed times that traces back to the earliest biblical patriarchs. Unlike the modern Hebrew calendar — a rabbinic lunisolar system — it divides the year into four perfectly equal seasons of exactly 91 days each.

Every year turns on a Wednesday — the intercalary Tekufah day, the 31st day that closes each season, standing outside the ordinary count. It was the fourth day of creation when the sun, moon, and stars were set in the sky as signs for seasons and years. The first full counted day, Day 1, falls on Thursday. The calendar aligns Sabbaths, festivals, and agricultural cycles in a perfect, unchanging pattern.

↳ See the seven-anchor argument for Thursday as Day 1 and Wednesday as the Spring Tekufah

This desktop app maps the ancient calendar onto the modern Gregorian system with precision astronomy, letting you see both timekeeping traditions side by side — day by day, month by month, year by year — with real solar, lunar, and planetary data for your exact location.

🛰️ Sourced directly from NASA JPL DE441 All four solar events — both solstices and both equinoxes — across 7,000 years are drawn directly from NASA's DE441 ephemeris — the most precise solar model available — and built into the app. The astronomical accuracy is not assumed; it is the data itself.

Beyond the Calendar

References and arguments behind the calendar

The original Bible calendar, the solar gate table of 1 Enoch 72, the starting day of the Enoch year, the chain of dates from the Exodus to the Crucifixion, the empires Daniel saw, the empires John saw — the references and arguments behind the calendar, each available as a full essay.

The Original Bible Calendar

The Calendar of Scripture

The calendar most Bibles are read against today is not the one the Bible itself describes. The case for the 364-day solar year — revealed in the Book of Enoch, assumed by the biblical narrative, and kept at Qumran — as the original calendar of scripture.

1 Enoch 72 — The Solar Gate Table

How the Sun Walks the Heavens

The Astronomical Book reduces the solar year to a single table: twelve months, six rising portals on the eastern horizon, and the day-by-day count of light and dark. The calendar's own account of how the sun keeps time — the mechanism every other topic here rests on.

Wednesday or Thursday?

A Lost Starting Point Recovered

Does the Enoch year begin on Wednesday or Thursday? Seven biblical anchors resolve only when Thursday is treated as Day 1 — with Wednesday standing as the Tekufah, the boundary day outside the count. The foundational calendar question.

The Chain That Holds

From the eclipse over Nineveh in 763 BC to Passover 32 AD — the chain of biblical dates anchored to Assyrian, Babylonian, Greek, and Persian records that survive outside Scripture. The Bible's chronology is verifiable, and this is how.
