Calendar-first custody planning

Build custody schedules that work on a real calendar

Create dated custody calendars around school nights, holiday overrides, exchange dates, and parenting-plan deadlines. Run overnight percentages, log actual visitation, and export printable exhibits — educational planning tools, not legal advice.

Start With The Right Tool

Each tool owns one planning question. Pick the page that matches what you need to calculate or print.

How CustodyBuilder Works

Three steps from planning question to printable output — full methodology is documented separately.

  1. Choose the planning problem

    Equal-time pattern, age-specific logistics, holiday overrides, overnight counts, or agreement clauses — each cluster page owns one question.

  2. Build or calculate with the tool

    Generator renders exchange dates on month cells. Calculators apply documented formulas. Templates outline clause structure without duplicating calendar math.

  3. Print or carry into a parenting plan

    Export PDF calendars for mediation prep. Attach percentage outputs and schedule exhibits to parenting-plan drafts — confirm filing format locally.

Why CustodyBuilder Is Different

  • Calendar-first

    Rotation patterns render as dated overnight cells — exchange markers show handoff days before pattern names get argued.

  • Tool-first

    Generator, calculators, and templates load above the fold. Editorial copy explains how to read output, not how to find a download button.

  • Reviewed methodology

    Calculator formulas, exchange-day logic, and cluster ownership rules are documented on the how-it-works page and reviewed on publish.

  • Printable outputs

    Month grids export with color keys and parent labels for mediation prep and parenting-plan exhibits.

  • Educational boundaries

    Planning material only — not court orders, case strategy, or filing advice. Disclaimers on every tool and guide page.

  • Cluster-specific guides

    Age guides do not repeat 50/50 rankings. Template pages do not duplicate generator mechanics. Holiday overrides defer to the holiday page.

Editorial Review & Methodology

The CustodyBuilder Editorial Team reviews tools and guides before and after publish updates.

  • Calendar generation — exchange days match the selected rotation ID and start date
  • Calculator parity — generator overnight summaries align with percentage calculator inputs
  • Cluster ownership — no duplicate FAQ grids or section titles across age, 50/50, holiday, or template pages
  • Educational boundaries — disclaimers visible; no legal advice or credential claims

Outputs are planning material. Confirm filing format, support determinations, and legal questions with a qualified professional.

FAQ

Homepage FAQ

Site-level questions only — rotation specifics live on pattern guides.

What is CustodyBuilder?

Custody planning tools and educational guides: calendar generator, percentage calculator, visitation log, Texas support estimate, templates, and age-specific schedule guides. Each page owns one search intent.

Which tool should I use first?

Use the custody schedule generator if you need dated exchange days on a month grid. Use the percentage calculator if you already have overnight counts. Use the visitation calculator to compare planned vs actual overnights.

Is CustodyBuilder legal advice?

No. Planning and education only. Tool outputs are not court orders. Confirm filing format and legal questions with a qualified professional in your jurisdiction.

How are calendars and calculators reviewed?

The editorial team checks exchange-day accuracy, calculator formula parity, internal link routing, and educational disclaimers. Methodology is documented on the how-it-works page.

Do I need an account?

No. Tools run in the browser without signup or payment.

Where are Texas-specific tools?

Texas child support calculator applies guideline percentages to net resources. Texas parenting plan template owns SPO calendar planning. Both are separate from generic custody tools.

How do I report an error?

Email [email protected] through the contact page with page URL, inputs used, and expected vs actual output. Calculator issues are verified against documented formulas.
