Editorial Policy

Last updated: May 2026

Original date guidance with visible assumptions.

This policy explains how Age in Days writes date calculation guidance, separates calendar math from outside rules, and corrects pages when users report a reproducible problem.

Editorial purpose

Each guide exists to help people understand a calendar result before they act on it. The site focuses on exact age checks, date spans, countdowns, working-day estimates, leap-year edge cases, school cutoff dates, and planning examples.

The editorial goal is not to turn a calculator result into official advice. It is to make the inputs, assumptions, limitations, and next checks easy to see.

Source quality

Explanations are written from visible calculator behavior, ordinary Gregorian calendar rules, and practical caveats that come up in real date questions. When a school, employer, agency, contract, or billing provider controls a date rule, the guide tells readers to check that source directly.

Tone and clarity standards

  • Clear assumptions before formulas.
  • Readable examples over jargon.
  • Explicit caution language for high-stakes use.
  • Different examples on different pages instead of repeated boilerplate.

Update cadence

Pages are checked for accuracy, edge cases, link quality, and language clarity when calculator behavior changes, when a user reports a reproducible issue, or when a guide needs clearer examples. Confirmed fixes are handled through the public corrections pathway.

Calculation explanations

Method notes describe the way the site treats dates: age mode measures from a birth date to a reference date, days-between mode measures the plain calendar span, countdown mode measures from the current calendar date to a target, and working-days mode removes Saturdays and Sundays only.

Those explanations are intentionally plain. They are meant to help readers reproduce the calculation and understand why a local rule might still need a separate check.

Limits we keep visible

Age in Days does not publish legal, medical, payroll, immigration, school-admission, tax, financial, or official eligibility advice. When a date result may affect one of those areas, the page should say that the calculator is a math aid and that the controlling rule must be confirmed separately.
