Chinese gender calendar (for fun)

A folk chart some families still pull out at barbecues. Entertainment, not embryology. Enter maternal age and birth month for a boy/girl novelty result. Estimate only — not medical advice.

Entertainment only — not science, not ultrasound, not medical advice.

Mother's age (Western years)

Birth month (1–12, Gregorian)

Enter age and birth month for a novelty result.

What this page does

We answer the search honestly: novelty only. Gregorian birth month + Western age convention is labeled on the form. Ultrasound and clinical screening are reality; this page is not.

No upsell to gender-reveal products. Nav stays under Fun so it cannot hijack the site’s medical-trust path.

When to use

Party games; curious fun beside real dating tools.

When not to

Any medical, shopping, or nursery-color seriousness. Do not mix into IVF counseling.

Assumptions

Deterministic folk-table toy from age × month. Gregorian month. Western age 18–45. EntertainmentOnly flag always true.

Examples

Age 30 · birth month March → Novelty Boy or Girl (fun).

Age 34 · birth month November → Opposite novelty for contrast.

Gotchas

Must treat as entertainment only — above the fold and near the result.

Lunar month conversion mistakes are common — we use labeled Gregorian simplification.

Ultrasound may disagree — and that is fine.

Not science, not medical advice.

How this is calculated

The math stays in your browser. Enter the dates you actually know, read the estimate, and treat clinic ultrasound dating as the authority when it disagrees.

Nothing here is medical advice, a diagnosis, or a substitute for prenatal care.

Enter the date(s) or numbers this page asks for.
Check the assumptions under the result and on Methodology.
Compare with your clinic portal if you have one.
Use related tools if you only have a different kind of date.
Confirm medical decisions with your clinician.

Novelty mapping from age and month — not a scientific model.
