Editorial Policy

How we research, prepare, publish, update and correct pregnancy education, calculator explanations and health-related information on Due-Date-Calculator.org.

Last Updated: August 23, 2026 Editorial Transparency Health Information Standards

Our Editorial Mission

Due-Date-Calculator.org aims to provide clear, accessible and useful pregnancy dating tools together with educational information that helps visitors understand pregnancy weeks, estimated due dates, conception timing, trimesters and common pregnancy-related topics.

We aim to present information in plain language without creating unnecessary fear, guaranteeing outcomes or presenting general online information as personalized medical advice.

Our core editorial principle: Pregnancy calculators should clearly communicate uncertainty, and health-related information should distinguish general education from individual medical care.

How Our Content Is Prepared

1
Topic Selection

We select topics that are directly useful to people researching pregnancy timing, fetal development, prenatal milestones, due dates and related educational questions.

2
Source Research

For health-related information, we aim to consult reputable medical and public-health organizations relevant to the topic.

3
Original Explanation

Information is organized and explained for our audience rather than simply reproducing source material.

4
Accuracy Check

Important measurements, pregnancy terminology, developmental milestones and medical guidance are checked against supporting references before publication where practical.

5
Safety Review

Health content is reviewed for overly definitive claims, misleading medical advice and language that could encourage visitors to ignore professional healthcare.

6
Publication and Updates

Published articles may be revised when new guidance, better sources, factual corrections or significant improvements become available.

Medical and Public-Health Sources

When appropriate, pregnancy and health-related pages may reference established medical institutions, professional organizations and public-health agencies.

Examples can include:

ACOG NHS CDC Mayo Clinic MedlinePlus Other Established Medical Sources

The exact sources used depend on the topic. References may be included within individual articles so visitors can review supporting information and learn more.

Originality and Added Value

Our goal is not to reproduce medical websites or simply combine information from external sources.

Pages are structured to provide additional usefulness through clear explanations, pregnancy-week organization, calculator context, comparisons, FAQs, practical interpretation and links between relevant tools and educational material.

Source attribution does not replace original content. External medical sources support factual information, while the structure and explanation of Due-Date-Calculator.org pages are prepared for our own audience.

Pregnancy Calculators

Calculator pages are designed to explain both the result and the limitations of the calculation.

For example, a pregnancy due date based on the last menstrual period is an estimate and may differ from pregnancy dating established by a healthcare professional.

Where appropriate, calculator results include contextual information such as estimated gestational age, trimester, estimated conception date or remaining time until an estimated due date.

Calculator transparency: We aim to avoid presenting mathematical estimates as medical diagnoses or guaranteed outcomes.

Pregnancy Week-by-Week Articles

Our pregnancy week-by-week articles aim to explain development specific to each stage rather than publishing the same article with only the week number changed.

Topics may include fetal development, maternal changes, fetal movement, prenatal appointments, pregnancy symptoms, testing, healthy pregnancy practices, labor preparation and when professional care is important.

Not every topic appears on every week page because medical relevance changes as pregnancy progresses.

Medical Claims and Certainty

Pregnancy and fetal development involve natural variation. Accordingly, we aim to avoid language suggesting that every pregnancy must follow exactly the same timeline.

We prefer wording such as:

  • “may”
  • “can”
  • “approximately”
  • “commonly”
  • “many people”
  • “varies between pregnancies”

when uncertainty or biological variation is relevant.

We also aim to distinguish estimates from confirmed clinical findings.

Medical Review and Professional Credentials

Due-Date-Calculator.org does not claim that content has been reviewed or approved by a physician, midwife or other licensed healthcare professional unless that claim is specifically stated on the individual page and can be supported.

References to organizations such as ACOG, NHS, CDC or Mayo Clinic mean that their published information may have been consulted as a source. It does not mean those organizations endorse, approve or review Due-Date-Calculator.org.

No implied endorsement: A source citation should never be interpreted as an endorsement of this website by the organization being referenced.

Health and Safety Standards

We aim to avoid content that could encourage unsafe self-diagnosis or delay appropriate professional care.

When relevant, articles may advise readers to contact a maternity service or healthcare professional for concerning symptoms such as reduced fetal movement, significant bleeding, severe pain or possible pregnancy complications.

Our content does not prescribe medicines or instruct visitors to stop prescribed treatment without professional guidance.

Updates and Review Dates

Health information can change as clinical recommendations and evidence develop.

Pages may therefore be reviewed and updated when:

  • important medical guidance changes;
  • a referenced source is substantially updated;
  • a factual error is identified;
  • new information improves the usefulness of the page;
  • links become unavailable;
  • the presentation can be made clearer or safer.

Where appropriate, pages may display a “Last Updated” date.

Corrections Policy

We aim to correct meaningful factual errors when they are identified.

A correction may involve changing inaccurate medical terminology, revising a measurement, replacing an outdated source, clarifying uncertain wording or removing a statement that is no longer supported.

Small spelling, grammar, formatting or design changes may be made without a formal correction notice.

Found an error? Visitors are welcome to contact us if they believe a factual statement, broken reference or calculator explanation should be reviewed.

Advertising and Editorial Independence

Due-Date-Calculator.org may display advertising or use third-party advertising services.

Advertising does not determine our pregnancy-week topics, calculator formulas, medical wording or editorial conclusions.

We aim to keep advertisements visually distinguishable from calculator controls, navigation and editorial information so users do not confuse advertising with website functionality or medical content.

Sponsored Content and Commercial Relationships

If Due-Date-Calculator.org publishes sponsored, promotional or commercially influenced material in the future, we aim to identify that relationship clearly where disclosure is appropriate.

A paid relationship should not be presented as independent medical evidence.

External Links

Our articles may link to reputable external sources for supporting information or further reading.

External websites operate independently from Due-Date-Calculator.org. Their content, availability, privacy practices and policies may change without our control.

Providing a link does not mean we endorse every statement, service or product available on the external website.

Country-Specific Guidance

Pregnancy recommendations can differ between countries and healthcare systems.

For example, vaccination schedules, screening programs, routine prenatal appointments and induction practices may differ between the United States, United Kingdom, Spain and other locations.

When a recommendation is country-specific, we aim to identify the relevant context instead of presenting it as a universal rule.

Calculator Limitations

Our tools perform calculations using the information entered by the visitor and the assumptions explained on the relevant calculator page.

Results can be affected by inaccurate input information, irregular menstrual cycles, uncertain dates and biological variation.

Calculator results should therefore be treated as estimates rather than substitutes for clinical pregnancy dating.

Editorial Responsibility

We are responsible for the content that appears on Due-Date-Calculator.org and aim to make reasonable efforts to publish clear, useful and responsibly framed educational material.

However, visitors remain responsible for obtaining professional healthcare when individual medical assessment is needed.
