ALWAYS HAPPENS

How we check a discovery

We separate the calendar calculation, the underlying biographical fact and the editorial explanation. Each can be right or wrong independently, so each needs its own check.

The calendar engine assigns January 1–February 28 to seven A groups and March 1–December 31 to seven B groups. February 29 is a special case. Group membership expresses permanent same-year weekday relationships inside a segment; it does not merge A and B groups or wrap across years.

Tests cover invalid dates, boundary cases, leap years, ordinary years, known examples and personal date clusters. A test result verifies the calculation it exercises; it does not verify a celebrity biography.

Public-figure records require a source and review date. A URL alone is not a verified fact. We prefer primary or authoritative biographical sources, surface uncertainty and avoid disputed dates in definitive claims. Commercial image permissions and attribution require separate review.

Original articles explain the discovery, show useful examples and link related material. Human review covers factual sourcing, originality, usefulness, rights and applicable publishing policies. Advertising readiness is our internal release gate; Google independently decides AdSense approval.

To request a correction, send the page URL, the claim in question and a supporting source through Contact. We review corrections rather than quietly changing the arithmetic to fit a more appealing story.
