Understanding the 2026–2027 Chodesh Rollover
Published at Elohim's Timepiece · March 26, 2026
If you have been following Elohim's Timepiece since 2023, you may have noticed something when the 2026–2027 schedule was released. The 12th Chodesh, which had been opening in early February for several years, began on March 6.

Nearly a full month later than the year before.
This post explains what happened — because what looks like a disruption is actually a demonstration. Not of instability in the heavens, but of exactly how a boundary-based system behaves when long-term drift finally meets a fixed threshold.
The sun did not change. The boundary did. And understanding that distinction is more important than the date itself.
A note for returning readers: it has been the practice here to publish one Chodesh at a time throughout the year, as each is observed and confirmed. This year, by request, the full 2026–2027 schedule is being released together so that those who need to plan ahead have a reference. The dates are based on meridian perfection data measured from Jerusalem and are as accurate as the method allows — but the commitment to observation remains. Each Chodesh will still be confirmed as the year unfolds.
Section 1: The Framework
Elohim's Timepiece is not a lunar calendar. It does not follow the 29-to-30-day rhythm of the moon's cycle. It is a solar instrument — built on the precision of the sun's meridian crossing, measured against defined constellation reference fields.
Each Chodesh begins at the first qualifying solar meridian perfection within a defined constellation field. The sun crosses the meridian — its highest point in the sky — every single day without variation. That crossing is the anchor. It does not wander. It does not fluctuate. It is the most stable measurable event in the daily sky.
The nearest approach to 0h 00m 00.00s, Azimuth 180° 00′ 00.0″ — true meridian perfection — within the correct constellation field marks the opening of a new Chodesh. Each solar year yields twelve such qualifying moments. Twelve Chodeshim. Not counted by the moon. Not counted by administrative convenience. Measured by the sun's nearest approach to the meridian within defined stellar boundaries.
All measurements are taken from Jerusalem — latitude N 31° 46′ 8.54″, longitude E 35° 12′ 58.79″, elevation 786m. This is not an arbitrary location. It is where the Temple stood. Where the daily tamid was offered. Where the appointed times were originally observed and reckoned.
What shifts slowly over centuries is the stellar background itself — the constellation reference fields — due to axial precession. The invisible lines hold. The background drifts. And when that drift accumulates enough to push a qualifying perfection across a boundary, the system resets.
That is what happened in 2026.
The biblical instruction given to Israel was that the appointed times were to be observable. The heavens were not meant to be tracked by calculation alone — they were meant to be seen. While the Disciples Table has not yet established with full confidence which specific stars served as the original reference points (though some strong candidates have been identified), the meridian-based method used here still requires active observation. The sun must be watched. The crossing must be measured. In that regard — whatever the precise stellar markers turn out to be — this method remains in agreement with the spirit of the instruction: the appointed times are found by looking up.
Section 2: Boundary-Based Systems Eventually Flip
Here is what the data shows when comparing the two years:

The 12th Chodesh of 2025 began on February 5.
The 12th Chodesh of 2026 began on March 6.
That is a shift of 29 days. For anyone watching the schedule closely, it raises an immediate question — did something go wrong?
Nothing went wrong.
For several years the qualifying meridian perfection fell securely within the earlier constellation window. Year by year the sun's perfection point drifted incrementally — as it always does — until one year it no longer qualified within the old boundary. It now qualified within the next one.
The system did not break. The system did exactly what it was designed to do. A boundary was crossed. The Chodesh rolled forward.
The 2026–2027 Elohim's Timepiece carries a notation on the 12th Chodesh entry: Rollover year — boundary crossing from February to March. That notation is there precisely so the record is clear. The meridian perfection data is published alongside every Chodesh entry so that any student can verify the measurement independently.
Section 3: Why the Duration Changed
The Chodeshim are not all the same length. Some run 22 days. Some run 34 days. This is not an error in the reckoning.
A Chodesh measures the interval between one qualifying meridian perfection and the next — not a fixed number of days. The sun does not move at a perfectly uniform rate relative to the stellar background. Its apparent speed varies slightly depending on Earth's position in its elliptical orbit. The result is that the intervals between qualifying perfections are not identical.
The 2026 rollover year produced a longer 12th Chodesh precisely because the qualifying moment had to travel further to reach the threshold of the next constellation field. This is not instability. It is precision.
Section 4: A Cycle Is Not a Container
There is something deeper here worth careful attention.
We tend to think of a month — any month — as a container. Thirty days in. New container begins. But that is not how Elohim's Timepiece works. A Chodesh does not end when a predetermined count expires. It ends when the sun reaches the next qualifying threshold.
The cycle completes at its boundary. Not before. Not after.

This means that the Mosaic day-count pattern — which begins at dawn, at boker, at the opening of morning light — follows the same logic at the daily level that the Chodesh reckoning follows at the monthly level. The day does not begin because a clock says it does. The day opens when the darkness of erev-boker has closed and morning begins. The Chodesh does not begin because a crescent moon is sighted. It begins when the sun reaches perfection within the appointed field.
His Way is a system of thresholds, not containers. And thresholds reveal the order — they do not disturb it.
Section 5: His Way and Man's Way — Side by Side
The 2026–2027 Elohim's Timepiece presents both systems in parallel for a reason.
Man's Way — the familiar lunar reckoning observed by most of the Jewish world — uses a different starting point for its months. Rosh Chodesh in Man's Way follows the lunar cycle: the appearance of the new crescent moon after sunset. The month names used in Man's Way — such as Nissan, Iyar, and Tishrei — were adopted from Babylonian usage during and after the exile, and do not appear in Torah reckoning during the days of Moses or King David. There, we read simply: the first Chodesh, the second Chodesh, the third Chodesh.
That is not a criticism of Man's Way. It is entirely acceptable to follow the traditional observance. But knowing His Way — the solar meridian pattern rooted in Jerusalem, in the Mosaic reckoning, in the structure placed in the heavens at creation — is invaluable. The two systems sometimes align. When they do, those dates are highlighted on the schedule. When they diverge, understanding why they diverge is itself an education.
For 2026, Man's Way places its 1st month (Nissan) beginning March 19. His Way — Elohim's Timepiece — places the 1st Chodesh opening on March 28. Both are presented so that you can see the heavens and the tradition together, without confusion.
Section 6: A Note on This Year's Weight
The 2026–2027 year carries an additional marker that should not pass unnoticed.

The 7th Chodesh — Rosh Chodesh of the Virgin/Betulah — opened on September 28, 2026. The schedule notes: Turn of the Year. And alongside Yom Teruah on that same day: +49th Shemitah Year begins.
This is a Shemitah year. The land is to rest. Debts are considered. The pattern of sevens — woven into the weekly Shabbat, into the seven-year agricultural cycle, into the counting toward Jubilee — reasserts itself in 2026.
It is fitting that this is also the year of the boundary rollover. A Shemitah year is itself a threshold event. The system does not drift past it unnoticed. The heavens mark it. The schedule reflects it.
Closing Reflection
The sun has not changed.
The boundary shifted — as it was always going to, as precession continued its long slow work across the centuries — and the qualifying moment moved to March. The 12th Chodesh arrived 29 days later than in 2025. The system held. The order remained.
Elohim's Timepiece has always been about reading what is already written in the sky — not imposing a human counting system onto the heavens, but observing the meridian, the boundaries, the faithful crossing of the sun day after day.
He made the moon for appointed times; the sun knows his entrance.
— Psalm 104:19
The 2026–2027 Elohim's Timepiece is published and available on the dedicated Timepiece page. Both the His Way and Man's Way schedules are included so that the appointed times can be followed in whichever system you observe — and so that both systems can be seen together, year by year, as the heavens continue to declare the glory of the One who set them in place.
A Note on Methodology
Elohim's Timepiece is measured from Jerusalem — latitude N 31° 46′ 8.54″, longitude E 35° 12′ 58.79″, elevation 786m. The day begins at dawn (boker) following the Mosaic pattern. Meridian perfection data is published alongside each Chodesh entry for independent verification.
There is at least one other community — based in Wales — whose solar Chodesh reckoning work is respected here. Their methodology differs in three ways: they use GMT rather than Jerusalem local solar time, they begin the day at sunset rather than dawn, and they apply IAU constellation boundaries rather than the field definitions used here. Any one of these three differences can shift a date. All three together explain why their published dates and these may diverge. Students are encouraged to examine both.
