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 — later it was recorded in the Dead Sea Scrolls — though the calendrical texts there place the year's start one day early, a shift most likely introduced during the Babylonian exile. It is a system of worship, festivals, and appointed times that traces back to the earliest biblical patriarchs. Unlike the modern rabbinic lunisolar calendar, 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.

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.
