1 Enoch: The 364-Day Year, Moon Phases, Seasons & Agricultural Time
Explore the Book of the Luminaries alongside modern scholarship, then follow calendar-based farming forward through medieval manuscripts, almanacs, Washington and Jefferson, phenology and today’s sensor-driven crop schedules.
What This Feature Covers
The Astronomical Book (1 Enoch 72–82) describes a 364-day schematic calendar with detailed observations of solar and lunar cycles, seasonal changes, rain, dew, winds, and changing daylight. R. H. Charles’s 1917 public-domain translation makes this text accessible for study. Modern scholars debate whether the calendar was observational, prescriptive, or sectarian, but its agricultural implications are clear: it represents one of the oldest known attempts to systematize the relationship between celestial observation and farming time. This feature page connects the Enochic calendar to the longer history of agricultural time-keeping—from Hesiod’s star-based farming calendar through medieval Books of Hours, colonial almanacs, phenological observation, and modern sensor-driven crop scheduling.

Attributed to Enoch; R. H. Charles (translator) · c. 300–100 BCE (translated 1917) · religious/astronomical text (public domain translation)
Complete public-domain translation of the Book of Enoch including the Astronomical Book (chapters 72–82). Describes the 364-day calendar, moon phases, equinoxes, solstices, and agricultural seasons within a cosmological framework.
Historical, not devotional.
The Enochic calendar is presented as a historical agricultural-observation system, not as religious instruction. Its 364-day schematic year is studied alongside other ancient calendars for what it reveals about the relationship between celestial observation and farming time. Modern scholarship on the Dead Sea Scrolls and Second Temple period provides context for the calendar's origin and use.
