THD Harmonic Calendar
Compare collective and DOB-anchored personal timing across Daily, Weekly, Monthly, and Yearly harmonic layers.
Calendar Settings
Your birth date is the sole anchor for personal harmonic timing.

Current Date Signal
Enter a date of birth and generate the calendar.
Color Legend
Emergence: start, explore, prototype
Contrast: review, correct, refine
Integration: finish, organize, implement
Mixed: matched layers indicate different phases
Neutral: no direct collective/personal match
Date Range Outlook
Generate the calendar to view the selected date range.
Purpose
The calendar compares the collective Turtle Calendar with a personal calendar anchored only to date of birth. A layer aligns when the collective and personal phases match in that same layer.
The interface is daily-first. A Daily match names the date. Weekly, Monthly, and Yearly matches provide support or background context.
Color Coding
| Color | Signal | Meaning | Practical Use |
|---|---|---|---|
| Emergence | Formation, opening, possibility, or a new direction. | Start, explore, prototype, test, or introduce. | |
| Contrast | Pressure, resistance, correction, or testing. | Review, repair, refine, slow down, or resolve weak points. | |
| Integration | Resolution, synthesis, completion, or stabilization. | Finish, organize, decide, publish, implement, or consolidate. | |
| Mixed | Multiple matched layers point to different phases. | Inspect the details and act selectively. | |
| Neutral | No direct collective/personal match. | Use ordinary judgment. |
The Three Phases
EmergenceFormation. A signal enters the field and begins taking shape.
ContrastTesting. The signal encounters pressure, limits, or correction.
IntegrationStabilization. Prior pressure resolves into a usable form.
Calculation Rules
| Layer | Collective Logic | Personal Logic |
|---|---|---|
| Daily | Original Turtle Calendar logic: March 20 year start, 364 harmonic days, skip days removed, then Cycle Day 1–28. Days 1–9 are Emergence, 10–18 Contrast, and 19–28 Integration. | Birth date is Personal Day 1. The personal Daily phase advances through the same repeating 28-day structure. |
| Weekly | Dominant collective Daily phase across the seven-day window beginning on the selected date; collective skip days are ignored. | Dominant personal Daily phase across the same seven-day window. |
| Monthly | The current 28-day harmonic block is assigned recursively through Emergence, Contrast, and Integration in repeating block order. | The current DOB-anchored 28-day block uses the same repeating block-phase order. |
| Yearly | The current position within the 364-day Turtle year is divided into Emergence, Contrast, and Integration sectors. | The current position within the DOB-anchored 364-day personal year is divided into the same three sectors. |
Layer Use
| Layer | Question | Use |
|---|---|---|
| Daily | What should I emphasize on this date? | Immediate actions and decisions. |
| Weekly | How should I pace the short-term period? | Scheduling, coordination, and near-term pressure. |
| Monthly | What project-cycle phase is active? | Campaigns, projects, and medium-range execution. |
| Yearly | What larger timing season is active? | Long-term direction and broad annual context. |
Daily-First Labels
| Condition | Label |
|---|---|
| Daily layer matches | Emergence Day, Contrast Day, or Integration Day |
| Daily and larger same-phase layers match | Phase Day with Weekly, Monthly, and/or Yearly Support |
| Larger layer matches without Daily match | Background Phase Alignment |
| Matched layers point to different phases | Mixed Harmonic Signal |
| No matching layers | Neutral Day |
Skip Days
March 19 and February 29 in leap years are outside the collective 364-day harmonic cycle. They receive no collective Daily phase. The personal DOB cycle continues normally.
Exports
Print creates a planning view. CSV includes full layer data and metadata. ICS creates one 7:00–7:15 AM event with a notification for each date in the selected range.
