How the Fixed Solar Calendar Contradicts
Both Enoch & Moses

Notice what Yahuah appointed for signs and seasons: BOTH the greater light (sun) AND the lesser light (moon). Not one. Both. This is not a suggestion — it is the foundation of how He designed His calendar system.

A calendar that determines all feast dates using only the sun’s position has effectively removed the moon from its appointed role. But Yahuah placed the moon in the heavens for a purpose, and we cannot set aside what He created for His own purposes.

This verse is direct and unambiguous. The moon is appointed for seasons — the same Hebrew word (moed) used for Yahuah’s appointed times throughout Leviticus 23. The moon is not optional in determining the moedim. It is commanded.

The Hebrew word for “month” is chodesh (חֹדֶשׁ), which comes from the root chadash — meaning new or renewing. The very word Scripture uses for “month” is tied to the renewal of the moon. This is not coincidence. It is design.

This is one of the most revealing passages in all of Scripture on this question. These merchants were not consulting a pre-printed calendar. They were watching the sky, waiting for the visible new moon to pass before they could resume commerce. You do not watch and wait for a mathematical formula. You watch and wait for something you can see. The entire complaint presupposes that the new moon was recognized by visible, naked-eye observation.

The Shunammite woman’s husband made this remark casually, without ceremony — the way someone speaks about something completely obvious. He looked at the sky and knew it was not a new moon. This kind of immediate, everyday recognition is only possible when a community routinely watches the moon with their own eyes. A mathematical calendar does not produce this kind of instinctive, visual awareness.

David could predict the new moon’s arrival within a single day — not because he consulted a chart, but because he had been watching the moon’s cycle with his own eyes. The same passage (verses 24–27) shows that King Saul also recognized the new moon had arrived without anyone announcing it formally. David, Jonathan, and Saul all shared the same common, sky-watching awareness. This is the culture of a people who observed the luminaries as Yahuah commanded.

Taken together, these three passages — a merchant watching the sky in Amos, a husband glancing up in 2 Kings, and David tracking the moon’s cycle in 1 Samuel — describe the same practice across centuries and contexts: the new moon was something people saw. It was never something they calculated in advance from a fixed table.

Genesis 1:14 tells us that the luminaries are for “signs” — the Hebrew word oth (אוֹת), meaning a visible signal or marker. A sign must be seen. It cannot function as a sign if it is bypassed by a formula.

Yahuah did not say: “Calculate the appointed times.” He said: “Let there be lights… for signs.” The entire design was built around observation — looking up at the sky and responding to what He placed there.

Consider what this means practically. Adam had no telescope. Moses had no astronomical instruments. No one in ancient Israel had access to the mathematical tables, star charts, or computational tools that modern fixed-calendar systems depend on. What they had were their eyes — and the luminaries Yahuah placed in the heavens specifically to be seen. The only method available to them, and the only method Scripture ever describes, was to go outside, look up, and observe what Yah had put there. That was not a limitation of their time. That was the design.

This is important because it means that no pre-set calendar — however carefully constructed — can replace the act of observing the luminaries that Yahuah Himself placed in the heavens. We do not create a calendar. We observe the one Yahuah already created and set in motion.

Addressing a Key Linguistic Claim

“Chodesh Does Not Mean New Moon” — Is That the Whole Story?

One argument sometimes made in favor of removing the moon from the calendar is rooted in Hebrew linguistics. It goes like this:

This is a carefully constructed argument, and it contains a kernel of truth: chodesh^H2320 does come from the root chadash^H2318, meaning to renew or make new. Yarach^H3394 is indeed the direct Hebrew word for the physical moon. These are accurate observations.

However, the conclusion drawn — that we are “not supposed to follow the moon” — goes far beyond what the linguistic evidence supports. Here is why:

1. Hebrew Describes Events Functionally, Not Always by Naming the Object

In Hebrew, as in most ancient languages, words often describe what something does rather than what it is. Consider two common English words: “heartburn” and “brainstorm.” Your heart is not actually on fire during heartburn, and your brain does not produce weather when you brainstorm — yet everyone immediately understands what both words mean because they describe the experience, not the biology. Hebrew works the same way.

Similarly, “rosh chodesh”^H7218+H2320 (“head of the month” or “beginning of the month”) describes the event — the start of a new cycle — without needing to name the moon in every instance. The fact that yarach^H3394 does not appear in every “new moon” verse does not mean the moon is absent from the concept. It means Hebrew is describing the observable event, not cataloguing the astronomical object.

2. Scripture Itself Directly Connects Chodesh to the Moon’s Cycle

We do not need to rely on linguistics alone. Psalm 81:3 removes all ambiguity:

In this single verse, Yahuah connects chodesh^H2320 (beginning of the month) with keseh^H3677 — a word that refers specifically to the full moon. These are not separate, unrelated events. They are two points in the same lunar cycle: the new crescent that opens the month, and the full moon that falls in the middle of it. If chodesh had no relationship to the moon’s cycle, this verse would make no sense.

3. The Context of 1 Samuel 20 Confirms Lunar Observation

In 1 Samuel 20, David and Jonathan speak plainly about “tomorrow is the new moon” as something they could anticipate — an approaching event they were watching for:

David knew tomorrow would be chodesh^H2320 because he was observing the sky. This is not mathematical pre-calculation. This is not a fixed chart. This is someone watching the heavens and knowing the new month was imminent. The entire account only makes sense in the context of lunar observation.

4. The Verse Used to Argue Against the Moon Actually Confirms the Moon

Numbers 10:10 is often cited as evidence that chodesh^H2320 simply means “beginning of months” with no lunar connection. But notice: this verse does not define how the beginning of months is determined. It simply instructs what to do when that beginning arrives.

Using Numbers 10:10 to argue against lunar observation is like using “observe the Sabbath” to argue about how to count to seven. The command tells us what to do; it does not eliminate the other passages that tell us how to count.

5. Psalm 104:19 Settles the Matter

Ultimately, the linguistic argument leads to a conclusion that directly conflicts with a plain declaration of Scripture:

The word translated “seasons” here is moedim^H4150 — the exact same word used throughout Leviticus 23 for Yahuah’s appointed feasts. Yahuah appointed the moon for the moedim. A linguistic argument about chodesh^H2320 cannot overrule a direct statement that Yahuah appointed the moon for the very feast days in question.

The distinction between worshipping the moon and watching the moon to mark time is one Scripture itself makes. Ancient Israel did not bow to the moon. They observed its renewal as Yahuah commanded — because He designed it to mark their months and appointed times.

What Does Enoch Actually Say?

Many who follow a fixed 364-day solar calendar do so because they believe it is taught in the Book of Enoch — a text they hold in high regard. We want to engage this honestly, because this is where the argument often begins and ends for those who embrace this system.

So let us look carefully at what Enoch actually says.

Enoch 72: The Sun’s Gates

Enoch 72 describes the sun moving through six gates over the course of the year, producing the pattern of seasons and varying day lengths. This chapter is the foundation of the 364-day solar calendar model — thirty days in most months, thirty-one days in the third, sixth, ninth, and twelfth months, producing a 364-day year.

We do not dispute that this is what Enoch 72 describes. The question is not what chapter 72 says. The question is what people do with it — specifically, whether they read it in isolation or in the context of everything else Enoch recorded.

Enoch 73–74: The Moon Is Also There

Immediately following the description of the sun’s gates, Enoch 73 and 74 give a detailed description of the lunar calendar. Enoch documents the moon’s phases, its waxing and waning, and how the lunar year of 354 days relates to the solar year of 364 days. He describes both luminaries working in tandem.

This is not a minor footnote. Enoch devoted entire chapters to the moon’s role in timekeeping. If the author of these writings intended a purely solar calendar that removed the moon from its timekeeping function, why did he spend so much of his account documenting the moon’s cycles in careful detail?

The Enochian Calendar Itself Still Tracks the Moon

Here is perhaps the most remarkable detail of all. If you examine any version of the 364-day fixed solar calendar closely, you will find that it still lists the moon’s phases — the full moon and the new moon — alongside every single date throughout the year.

Think about what that means. A system that insists the moon plays no role in determining months and feast dates still tracks the moon’s phases day by day. The moon is present on every page — it is simply not being used for its Yahuah-appointed purpose.

If the moon were truly irrelevant to the calendar, why document it at all? The answer is that even those who constructed this system could not escape the reality that Yahuah’s luminaries are both present, both active, and both relevant — exactly as Genesis 1:14 and Psalm 104:19 declare.

Moses Is Even Clearer

Whatever one believes about the Book of Enoch, Yah’s Word is not in question among those who walk this path. And Scripture is unambiguous:

Moses recorded that Abib is a month to be observed — not calculated in advance by formula. The word “observe” (shamar) means to watch, to guard, to keep by looking. It is an act of attention to what Yahuah placed in the sky, not the execution of a predetermined chart.

So here is where we land: the fixed solar calendar does not align with what Yah’s Word plainly teaches — and it also lacks clear support from the very source it claims as its foundation, since Enoch’s own account documents the lunar calendar alongside the solar one. But more importantly, even if those chapters were absent, Moses alone is sufficient. Torah does not require Enoch to establish the moon’s role. Psalm 104:19 stands on its own. Genesis 1:14 stands on its own. The calendar question is settled in the 66 books before we ever open another source.

Many believers who embrace a fixed solar calendar do so through the Book of Jubilees rather than — or alongside — 1 Enoch. Jubilees is an ancient text, likely written in the 2nd century BCE, that retells Genesis and Exodus and includes its own calendar system. Like 1 Enoch, multiple copies were found among the Dead Sea Scrolls, suggesting it was highly regarded at Qumran. It commands significant respect in some Torah-observant and Hebrew Roots communities, and its calendar claims deserve an honest response.

What Jubilees Says About the Calendar

Jubilees describes a year of 364 days, divided into four seasons of 91 days each, with each season containing exactly 13 weeks. Like the Enochian calendar, this produces a solar year in which the feasts always fall on the same day of the week, every year, without variation. Months in Jubilees are also fixed at 30 days, with intercalary days added at the end of each quarter.

This is the same fundamental structure as the Enochian calendar — a fixed solar year that does not require observing the new moon to determine the beginning of months or appointed times. Proponents argue that Jubilees represents an ancient priestly calendar predating the rabbinic system, and that observing it is more faithful to Scripture than following lunar months.

Applying the Plumb Line

The same test we applied to the Enochian calendar applies equally here. The question is not how ancient Jubilees is, nor how many Dead Sea Scrolls copies were found, nor how sincerely its followers hold it. The question is: does its calendar system remove the moon from the role Yahuah assigned it in Scripture?

A 364-day fixed solar calendar — whether drawn from Jubilees, 1 Enoch, or any other source — determines feast dates without observing the new moon. The moon plays no functional role in marking the beginning of months or appointed times. That is a direct conflict with both of these passages, regardless of which extra-biblical text is used to support the system.

Jubilees itself, like 1 Enoch, does not resolve this conflict — it creates it. When Jubilees’ calendar is placed alongside the plain testimony of Psalm 104:19 and Genesis 1:14, the 66 books must govern. This is not a dismissal of Jubilees as a historical document. It is simply the application of the standard Scripture itself demands.

The 66 Books Remain Our Plumb Line

We recognize that sincere believers hold various ancient writings in high regard, and we do not dismiss that sincerity. However, our standard as an assembly is firm:

And in this case, the 66 books and the extra-biblical source being invoked are pointing in the same direction: both luminaries belong in Yahuah’s calendar. The fixed solar calendar finds itself in the remarkable position of contradicting both.

We are not saying that anyone who follows a different calendar is acting in bad faith. Many are sincere, searching believers doing their best to honor Yahuah. We simply must be faithful to what Scripture says — and in this case, to what even Enoch says — even when it requires us to stand apart from others.

Note: A future teaching series will address the extra-biblical books more thoroughly. This is a conversation worth having carefully and fully, and we look forward to that study together as a community.

Addressing an Important Question

If a Fixed Calendar Is “Close,” Does the Method Really Matter?

Some may reason: “If the fixed calendar produces dates that are near the right time of year, does the method of calculation really matter?”

We believe it does, and here is why:

1. Obedience to Yahuah’s design matters.
   He placed the luminaries in the heavens for a specific purpose. Using a system that bypasses them is not honoring that design — even when the intent is sincere. Yahuah is an Elohim of order, and He established the order of the heavens for our benefit. We honor Him by following it.
2. When lunar and solar cycles diverge, fixed calendars drift.
   Every few years, the difference between the lunar year (~354 days) and the solar year (~365 days) accumulates to more than one month. Fixed calendar systems manage this with mathematical insertions. Our assembly, by contrast, simply waits for the visible new moon to appear after spring is established. No manual correction is needed — we observe what Yahuah put in place.
3. The feast dates themselves depend on the correct starting point.
   Pesach is on Abib 14. Yom Teruah is the first of the seventh month. Sukkot begins the 15th of the seventh month. If the month begins on the wrong day because the new moon was bypassed, then Abib 14 is not actually Abib 14 — regardless of what a chart says. The appointed time is the appointed time, and Yahuah set it by His luminaries.

Scripture Is Our Foundation

We hold firmly to this principle:

The 66 books are our plumb line — a term borrowed from ancient construction, where a weighted string was dropped to establish a perfectly straight, true vertical. Builders used it to test whether a wall was genuinely upright or only appeared to be. Yahuah uses the same image in Amos 7:7–8, holding a plumb line against Israel to test whether they measured up to His standard. In the same way, the 66 books are the fixed, true standard against which all other sources must be measured — not the other way around. We encourage every believer to search the Scriptures on this question (Acts 17:11, 2 Timothy 2:15) and reach their own conclusions before Yahuah.
