This appendix supports The 364-Day Calendar: Weeks, Seasons, and Sacred Time. It provides the month table, the exact distinctions between the three schematic counts, and a short explanation of the proposed solar adjustment.

1. The twelve-month table
Every quarter contains 30 + 30 + 31 = 91 days = 13 weeks. The numbered day ranges below are inclusive positions within one ordinary 364-day year; they are not elapsed intervals between two dates.
For the weekday example, Month 1, Day 1 is Wednesday. This is the Enochian starting convention used in File 12 §6.3.3, associated with the fourth-day creation of the heavenly lights. The table demonstrates its arithmetic without specifying a modern civil date, a clock time, or an ancient local day-boundary practice.
| Quarter | Month | Days | Numbered days of the year | First weekday |
|---|---|---|---|---|
| 1 | 1 | 30 | 1–30 | Wednesday |
| 1 | 2 | 30 | 31–60 | Friday |
| 1 | 3 | 31 | 61–91 | Sunday |
| 2 | 4 | 30 | 92–121 | Wednesday |
| 2 | 5 | 30 | 122–151 | Friday |
| 2 | 6 | 31 | 152–182 | Sunday |
| 3 | 7 | 30 | 183–212 | Wednesday |
| 3 | 8 | 30 | 213–242 | Friday |
| 3 | 9 | 31 | 243–273 | Sunday |
| 4 | 10 | 30 | 274–303 | Wednesday |
| 4 | 11 | 30 | 304–333 | Friday |
| 4 | 12 | 31 | 334–364 | Sunday |
| Year | 12 months | 364 | 1–364 | Next year: Wednesday |
The annual seasonal days occupy positions 91, 182, 273, and 364, the final day of each quarter. All four count within the 52 weeks. They are not days outside the weekly cycle.
The weekday for any numbered day is found by advancing day number − 1 days from Wednesday. Thus Month 1, Day 14 is Tuesday, and Day 15 is Wednesday. Each date repeats its own weekday in this calendar; a Wednesday year-start does not make every festival Wednesday.
The equal 91-day quarters are the calendar’s divisions. They should not be mistaken for a claim that the four astronomical intervals between equinoxes and solstices are exactly equal.
2. Three counts and their relationships
| Count | Derivation | Role in this framework |
|---|---|---|
| 336 days | 24 × 7 × 2 = 48 × 7 | Two schematic rotations of the 24 priestly courses |
| 360 days | 12 × 30 = 4 × 90 | Equal-month, prophetic reckoning |
| 364 days | 360 + 4 = 4 × 91 = 52 × 7 | The complete-week Enochian calendar year |
Two different additions reach 364:
| Starting count | Addition | Completed count | Meaning |
|---|---|---|---|
| 360 days | 4 days | 364 days | Four annual seasonal days |
| 336 days | 4 × 7 = 28 days | 364 days | Structural bridge of four weeks |
File 12 §§6.3.1–6.3.2 preserves the four-week bridge as a structural corollary. The 24-course roster and weekly service pattern have their own source basis, summarized in §6.3.1a; the precise historical administration of festival weeks requires separate evidence. The four-week difference is not the same thing as the four annual seasonal days.
Likewise, distinguishing a 360-day reckoning within the complete year does not shorten an elapsed 364-day interval. In Charles’s translation, 1 Enoch 75:1–2 distinguishes the four service days, while 82:4–6, 11 makes their inclusion in the whole year explicit. These complementary passages govern the explanation in the main article.
3. The solar gap and a proposed leap-week model
File 12 §5.1 uses approximately 365.2422 days as a tropical-year reference. Against that reference:
365.2422 − 364 = 1.2422 days per year.
One week of discrepancy accumulates in approximately 7 ÷ 1.2422 = 5.64 years. That quotient illustrates the size of the gap; it is not, by itself, an intercalation schedule. The measured tropical year also varies with epoch and should not be treated as one permanently exact decimal.
The Detailed Study explores a constructed schedule with a leap week after years 6, 12, 18, 24, 30, 36, and 40 of a 40-year block. Its successive intervals are six years six times, followed by four years. This is a proposed reconstruction, not a rule stated in the ancient passages cited here.
| Proposed block | Ordinary days | Added whole weeks | Total days | Mean days per year |
|---|---|---|---|---|
| 40 years | 40 × 364 = 14560 | 7 × 7 = 49 days | 14609 | 365.225 |
| 400 years | 400 × 364 = 145600 | 71 × 7 = 497 days | 146097 | 365.2425 |
Ten ordinary 40-year blocks supply 70 leap weeks. One additional week brings the 400-year total to 71. Any placement of two weeks near the final boundary must preserve that total: one is the last regularly scheduled week, and only one is extra beyond the 70. The table gives the block arithmetic, not a fully dated historical calendar.
The resulting mean equals the Gregorian calendar’s mean. Its rule supplies 97 leap days in 400 years, so 400 × 365 + 97 = 146097; see the U.S. Naval Observatory’s calendar explanation. Equal block lengths do not establish ancient use of the proposed schedule or exact agreement with the seasonal cycle at every epoch.
There is also a different construction in File 12 §7A: a 360-day base with seven 30-day leap months in 40 years, giving 40 × 360 + 7 × 30 = 14610 days, or a 365.25-day mean. It must remain separate from the 364-day, leap-week proposal above.
