1. Book of Jubilees – Core Rules
- Solar Calendar Requirement – Year = 364 days; festivals must remain fixed, never shifting by lunar months (Jubilees 6:30–38).
- Omitting or adding days corrupts the appointed times.
- Festival of Weeks (Shavuot / Firstfruits of Wheat) – Observed in the third month, middle of the month (15th day); tied to Noah, Abraham, and the giving of the Law (Jub. 6:15–21).
- Passover – 14th day of the first month; no leaven from 14th to 21st (Jub. 49:1–23).
- Strict ban on leaven; penalty for eating it = “cut off from Israel.”
- Must be kept in its season with no change of date.
- Feast of Unleavened Bread – 15th–21st day of the first month; holy convocations on the first and seventh day.
- Day of Atonement – 10th day of the seventh month; fast, no work, repentance for all sins (Jub. 34:17–19).
- Feast of Booths (Sukkot) – 15th–22nd day of the seventh month; 8th day = solemn assembly.
- Trumpets – 1st day of the seventh month; rest and memorial of blowing.
- Prohibition Against Mixing Festivals with Pagan Rites – Jubilees warns against following Gentile calendars or blending appointed times.
2. Book of Enoch – Observational & Priestly Duties
- Enoch’s Calendar – Year fixed at 364 days, with four quarters of 91 days; each quarter begins with a seasonal marker day (Enoch 72–82).
- Priestly Watch – Angel Uriel teaches Enoch the exact days to keep festivals so “sinners will not err” in observing them.
- No Changing Appointed Times – Moving the days is a cause of judgment.
- Seasonal Gates – Each major feast is aligned with the solar gates; spring equinox marks the year start.
- Sabbath Alignment – The appointed feasts are bound to the same weekday each year because of the fixed solar cycle.
3. Leviticus (Torah Law – Priestly Instructions)
- Leviticus 23 – Lists the appointed times of YAH:
- Sabbath – Weekly rest on the 7th day; no work.
- Passover – 14th day of the first month at twilight.
- Unleavened Bread – 15th–21st day; holy convocations on the 1st & 7th.
- Firstfruits – On the day after the Sabbath during Unleavened Bread; priest waves the sheaf.
- Feast of Weeks (Shavuot) – Count 7 Sabbaths (50 days) from Firstfruits; offer new grain.
- Trumpets – 1st day of the seventh month; memorial with blasts, no work.
- Day of Atonement – 10th day of the seventh month; afflict your soul, no work.
- Feast of Booths – 15th–22nd day of the seventh month; 8th day = solemn assembly.
- Offerings & Sacrifices – Specific animal and grain offerings for each feast.
- No Work Command – On certain feast days, work is forbidden.
4. Deuteronomy (Covenant Enforcement)
- Deut. 16 – Emphasizes where and how to keep the feasts:
- Passover & Unleavened Bread – Keep at the place YAH chooses; no leaven in all your territory for 7 days.
- Feast of Weeks – Rejoice with Levites, strangers, orphans, and widows; freewill offerings according to blessing.
- Feast of Booths – 7 days of rejoicing; all males appear before YAH 3 times a year (Passover, Weeks, Booths).
- Central Sanctuary – Sacrifices must be offered at YAH’s chosen place, not anywhere you wish.
- Justice & Righteousness – Feasts tied to obeying judges and priests; no pagan altars.
✅ Key Unifying Rules Across All Texts:
- Fixed 364-day solar year (Enoch/Jubilees) → prevents drift.
- Holy Days are covenant signs and cannot be altered.
- Observed in order given by YAH—any change is sin.
- No mixing with pagan rites or foreign calendars.
- Observance requires Sabbath-level rest on certain days.
- Central place of worship for sacrificial feasts (Deuteronomy).
