How CustodyBuilder Works
This page documents how calendars, percentages, calculators, templates, and guides are produced and reviewed — the methodology reference for the entire site.

How Calendar Generation Works
The custody schedule generator maps a repeating rotation block onto real dates.
Pattern selection
Each rotation ID (2-2-3, 2-2-5-5, week-on/week-off, etc.) defines which parent holds which weekday in the repeating fortnight or week block.
Start date anchor
The order effective date sets day one. Mid-month starts produce a partial first week — that is correct behavior, not a bug.
Cell rendering
Each overnight paints Parent A or Parent B on the month grid. Exchange days appear at block boundaries.
Export
PDF includes color key, month grid, and parent labels for exhibit attachment.
How Parenting Percentages Are Calculated
Overnight counts drive the percentage — not hours or partial days unless an order specifies otherwise.
Parent % = (Parent overnights ÷ Total overnights) × 100
- Generator summaries count overnights in the preview cycle as planning estimates
- Custody percentage calculator accepts manual overnight totals for court discussion inputs
- Visitation calculator compares planned vs actual overnights over a labeled tracking period
How Schedule Guides Are Reviewed
Each guide cluster owns one search intent. Reviews check for cluster overlap before publish.
- Unique H2 ownership — no duplicate section titles across age, 50/50, holiday, or template pages
- Tool-first hero with generator or calculator above the fold
- Boundary paragraphs defer percentage math, Texas law, and pattern rankings to the owning page
- 7–8 FAQs unique to the page topic — no duplicated schedule FAQ grids
- AI slop phrase scan — operational language only
How Templates Are Structured
Template cluster pages separate rotation rules, calendar layout, agreement clauses, and Texas SPO language.
-
Custody schedule template
Owns recurring rotation, exchanges, summer placeholders — not legal clauses.
-
Custody calendar template
Owns printable month grid and color coding — not rotation drafting.
-
Parenting plan template
Owns agreement sections and clause hierarchy — not calendar design.
-
Texas parenting plan template
Owns SPO calendar, 100-mile rules, summer notice — not generic plans.
How Texas Tools Are Limited
Texas pages own Texas-specific math and possession language — generic tools defer here.
- Texas child support calculator applies guideline percentages to net resources — not overnight counts
- Texas parenting plan builder previews SPO weekends — not 50/50 pattern rankings
- Official Texas resources linked for filing context — not interpreted as legal advice
What CustodyBuilder Does Not Do
- Decide holidays automatically in the base generator — holiday overrides are built on the holiday custody page
- Set child support amounts from parenting time alone in Texas — income-based guidelines are separate
- Log historical visitation in the percentage calculator — use the visitation calculator
- Provide legal advice, court predictions, or filed forms

Editorial Review Standards
- Calculator output must match documented formulas
- Generator exchange days must match pattern engine for the selected rotation ID

- Internal links must route to the page that owns the topic
- dateModified updates when tool logic, examples, or review scope changes
