What Is the Chinese Gender Calendar and How Does It Work?

The Chinese Gender Calendar, also known as the Chinese Birth Chart, is a centuries-old method believed to predict a baby’s gender based on the lunar age of the mother and the month of conception.
According to ancient Chinese tradition, this chart was discovered in the Qing Dynasty’s royal archives and later shared with the public as a cultural treasure.

Unlike modern scientific methods, this chart follows the Chinese lunar calendar rather than the Western Gregorian calendar.
It combines two important factors:

• Mother’s Lunar Age (converted from your actual birth date)
• Lunar Month of Conception

By matching these two values on the chart, the calendar suggests whether you are likely to have a boy or a girl.

While not scientifically proven, it remains one of the most popular baby gender prediction tools worldwide – especially among parents who enjoy exploring ancient wisdom alongside modern planning.

How to Use the Chinese Gender Calendar (Step-by-Step Guide)

How to Use the Chinese Gender Calendar

Using the Chinese Gender Calendar is simple once you understand how the lunar system works.
Here’s a clear step-by-step guide to get your result accurately:

Step 1: Find Your Lunar Age

The Chinese calendar doesn’t use your actual (Gregorian) age.
It’s based on your lunar age, which may be one or two years older than your real age.
Our calculator automatically converts this for you – no math needed.

Step 2: Identify the Conception Month

Choose the month when conception occurred or is expected.
This is equally important because the Chinese calendar follows lunar months, which don’t align exactly with Western months.

Step 3: Match Your Age and Month on the Chart

Locate your lunar age on the vertical axis and your conception month on the horizontal axis of the Chinese Baby Gender Chart.
Where the two intersect reveals the predicted gender – Boy (often shown in blue) or Girl (in pink).

How Accurate Is the Chinese Gender Calendar?

The Chinese Gender Calendar has been used for generations but how accurate is it really?
While many parents around the world claim that it correctly predicted their baby’s gender, scientific studies suggest that the results are mostly coincidental.

According to surveys, the chart’s accuracy ranges from 50% to 70%, which is about the same as random chance.
However, the charm of this calendar lies not in its precision but in its cultural significance.
It connects modern families to ancient Chinese beliefs about balance, timing, and destiny.

Our advice:

• Enjoy the calendar as a fun tradition, not a guarantee.
• For medical accuracy, consult an ultrasound or a healthcare professional.
• Use it to plan or predict with curiosity, not certainty.
