The Dead Sea Scrolls preserve a 364-day solar calendar rooted in the Book of Enoch and used long before the Temple periods — 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.
A complete research and devotional tool — precise astronomy, ancient timekeeping, and biblical cycles in a single offline desktop app. All add and edit features are fully enabled in the download.
Toggle between a side-by-side Gregorian + Enoch Calendar view or a pure Enoch Calendar-only view. Every day cell shows both dating systems together, with all holidays and events visible at a glance.
Passover, Firstfruits, Shavuot, Yom Kippur, Sukkot, and more — placed on their exact biblical dates. Layer in public holidays from over 80 countries, colour-coded by nation.
Each Tekufah day is visually split — left half shows the outgoing season, right half the incoming. The Leap Week is inserted based on the UTC spring equinox, making it consistent for every user regardless of timezone. A drift chart tracks the solar year across millennia.
A live sliding timeline shows exactly where any year sits within the 7-year Shemitah and 50-year Jubilee cycles, with markers placed on every calendar day.
The ten Enoch Weeks and their seventy Days are mapped as scrollable timelines across all of history — from creation to the final age — with your current position marked live.
Click any day for precise sunrise, solar noon, and sunset times for your GPS coordinates. Moon phase, moonrise, moonset, and full moon times are shown alongside hourly altitude and azimuth data for the Sun, Moon, and all visible planets.
Add custom events on either calendar system with repeating rules, reminders, and countdown timers. Events can be linked together in sequences and displayed as a zoomable master timeline.
