Curiosity starts it.
Evidence earns it.

Follow the source

Calendar stories use preserved Retrosheet game records, checked against the qualified 1899–2025 Phillies regular-season population. Player-season batting uses the preserved SABR Lahman baseline through 2025, with Phillies stints isolated. Each article identifies its own scope and source. Detailed source records are retained for verification and corrections.

Count the right thing

A consecutive calendar-year run differs from consecutive appearances on a date. Doubleheaders, years without games, ties and unresolved results affect the count. We preserve source dates and historical opponent names instead of guessing.

Make room for uncertainty

Postseason and provisional 2026 data are excluded here. Pre-1899 calendar records are not part of the qualified calendar population. A Phillies dataset maximum is not automatically an MLB record. We do not infer individual plays from final scores.

Patterns are not predictions

Calendar Curse, Calendar Magic and Calendar Fireworks are editorial names. Dates do not cause wins, losses or scoring. The historical record supplies observations, not forecasts or betting guidance.

Transparent editorial status

All five articles in this edition have completed factual and editorial verification. This edition uses approved graphics without fabricated historical photographs or player likenesses. Source credits and licensing notices accompany the historical evidence.
