Chinese Gender Calendar 2026
The Chinese chart is an ancient tradition that, according to belief, predicts whether you're expecting a boy or a girl by crossing the mother's lunar age with the month of conception. Here we explain how to read it, with the reference chart.
⚠️ Important: the Chinese gender calendar is a traditional curiosity with no scientific basis. Its accuracy is like flipping a coin (~50%). It does not replace an ultrasound or any medical test. Take it as a game.
✦ What is the Chinese gender calendar?
Legend says the original chart was found in an imperial tomb near Beijing. It crosses two pieces of data: the mother's lunar age at conception and the lunar month of conception. At the intersection, the chart indicates "boy" or "girl". It is one of the most popular gender predictions in the world, though purely by tradition and entertainment.
✦ How to use the chart in 2 steps
1. Calculate your lunar age
In Chinese tradition, pregnancy counts as the first year of life, so 1 year is usually added to your real age. Example: if you are 28, your lunar age is 29.
2. Identify the lunar month of conception
Find the month when conception happened (ideally converted to the Chinese lunar calendar). Cross your lunar age (row) with the month (column) and read the result.

Traditional reference version, for entertainment. Variations circulate; none have scientific validity.
✦ Is it reliable? What science says
No. A baby's sex is determined by the chromosome (X or Y) of the sperm at fertilization, something no chart can predict from the mother's age or the month. Studies reviewing the Chinese chart find accuracy equivalent to chance. To know the sex for certain, the way is medical testing (ultrasound, genetic analysis).
