“I have assigned to you 40 days, a day for each year.”
Ezekiel 4:6 (BSB), excerpt
For a first reading, begin with Ezekiel’s 430 Days. Use Part 1 to understand the charts, then follow the subjects that interest you.
Each study states its calendar, starting date and counting rule. Symbolic dates express a comparison on the day–year scale; ordinary historical dates and Rounded calculations keep their own conventions.
Part 1 · Method and charts
The working charts, calendar choices and starting reference points.
Charts and datums
The chart collection for Ezekiel, the Temple, Exodus and Flood.
Chart methodology
How dates, calendars and starting points are used to construct the symbolic charts.
Canonical starting points
Part 2 · Ezekiel
The explicit day–year sign and its dated prophetic setting.
2A · Ezekiel’s 430 Days
Begin with the sign: 390 days for Israel and 40 for Judah. Continue to its dates and exile comparisons.
2B · Covenant and the 430-year corridor
The 430-year corridor and its covenant comparisons in Ezekiel’s chart.
Canonical starting points
Part 3 · Temple, Exodus and Conquest
From foundations and wilderness years to inheritance and rest.
Temple foundations and rebuilding
Solomon’s and Zerubbabel’s foundations, with a shorter detailed companion and an expanded symbolic-date study.
Moses and the Exodus
Forty days, forty years and the phases of Moses’ life.
Conquest and the year of rest
The Jordan crossing, the years of conquest and the land’s rest, with Caleb’s testimony as the setting.
3B · Additional Exodus and Conquest patterns
Further calendar comparisons involving Sinai, covenant, tabernacle and inheritance.
The Exodus at the center
Two 490-year spans meeting at the Exodus, with the selected variants and schematic endpoint explained.
Canonical starting points
Part 4 · Flood and new creation
The narrative sequence, symbolic chart and seasonal comparisons.
Flood dates and durations
The rain, rising waters, Ark’s rest, bird sendings and departure. Biblical dates and calculated day counts are distinguished.
Ark dimensions and the 600-year pattern
The proposed comparison between the Ark’s dimensions and the ages and eras of Noah and Shem.
4A · Flood datums and new creation
The starting dates used for the symbolic Flood chart and its new-creation comparisons.
4B · Seasonal columns and Mirrors
Seasonal chart columns, selected span expansions and the stated Mirror operations.
4C · Jacob and the pattern of sevens
Jacob’s two seven-year periods and the dove’s two waits, compared with later periods of restoration.
Canonical starting points
Part 5 · Birth of Jesus and the Key of 23
The Gospel framework, calendar datums and successive Capstone constructions.
Capstone reading order: 5A → 5B → 5C → 5D. The shared calendar-datum appendix supports the whole sequence. These studies also develop exploratory number sets; their tables state the local rules and assumptions.
The birth of Jesus: eight days and forty days
Circumcision, purification and presentation introduce the Gospel framework before the Capstone calculations.
5A · Symbolic dates and calendar frames
Birth-related symbolic dates and the Julian and Gregorian calendar frames.
5B · Expanding the number sets
The starting coordinates and the Key of 23 rule used to expand them.
5C · Sums and collective dates
The separate sums of the sets’ two halves and their larger comparisons.
5D · Expansion across the Mirror
The starting set, its reflected copy and the rule governing further expansion.
Shared calendar-datum appendix
The January 1 circumcision anchor, inclusive counting and the Julian–Gregorian two-day relationship.
Part 5 companion · The Birth and Cross of Christ in Symbolic Time
The concluding study in the Christ day–year series and a bridge between Books 1 and 2. It follows the birth and Passion comparisons through the Key of 23, the Day of Atonement, and the renewal of Creation.
Alpha, Creation, and Christ · 1/137
A separate companion to the Birth–Cross study, following 1/137 through the patriarchal lifespans, the land promise, Creation and Christ, and symbolic feast-day residues.
Canonical chronology controls
These files supply chronological settings and established operators. The linked studies explain the additional number-set rules.
Related studies and additional research
Separate operations and research supplements alongside the numbered reading sequence.
5E · Related Rounded inverse study
The Rounded inverse study associated with Part 5E. Numerical reversal is a separate operation from Part 5D’s set expansion.
Earlier Temple research
A longer Temple-template discussion with its own numbering. Read it as earlier extended research.
5F · Exploratory supplement
Further Key of 23 constructions, presented as an exploratory appendix to the Part 5 studies.
Companion study: a bridge between Books 1 and 2
The 360 calendar’s symbolic day-year testimony is developed separately in The Birth and Cross of Christ in Symbolic Time, a companion study completing the Christ sequence in the Day–Year Studies series and connecting Books 1 and 2. It follows the birth and Passion comparisons through the Key of 23, the Day of Atonement, and the renewal of Creation.
