About

Waiting for a gender reveal is often filled with anticipation. Throughout history, cultures have developed distinct methods to guess the sex of a child before birth. While modern ultrasound and NIPT tests provide medical accuracy, folklore methods remain a popular source of entertainment and tradition. This tool is an aggregator: it runs your data through the Chinese Gender Chart (Qing Palace logic), the Maya methodology, and Blood Renewal theory simultaneously.

It also incorporates a weighted score based on "Old Wives' Tales" regarding symptoms like cravings and sleep position. The final output is a probability card, purely for entertainment purposes.

This theory posits that a woman's blood renews every 4 years and a man's every 3. The parent with the "younger" blood at conception is said to determine the gender.
Folklore says sweet cravings indicate a girl and salty/savory indicate a boy. Scientifically, cravings are linked to nutritional needs and hormones, not the baby's sex.
