Chinese gender chart 2026

The Chinese gender chart (also called the Chinese birth chart or Chinese gender calendar) is a 700-year-old tradition that claims to predict whether you're having a boy or girl based on two values: the mother's lunar age at conception and the lunar month of conception. Here's how to read it for 2026 — and what the science actually says.

How the Chinese gender chart works

The chart is a grid with two axes:

• Vertical axis: the mother's lunar age at conception (18 to 45)
• Horizontal axis: the lunar month of conception (1 to 12)

You find the cell where your lunar age row meets your conception month column. The cell says either “boy” or “girl.” That's the prediction.

The trick is that lunar age and Gregorian (Western) age are not the same. In the Chinese system, you're considered 1 year old at birth, and you gain a year at Chinese New Year (not on your birthday). So your lunar age is usually 1-2 years higher than your Western age.

Calculating your lunar age for 2026

To convert your Western age to lunar age:

1. Start with your current Western age
2. Add 1 year (because you were “1” at birth)
3. If your birthday hasn't happened yet this lunar year (i.e., between Jan 1 and Chinese New Year), add 1 more year

For example, a 28-year-old Western age woman conceiving in 2026 would typically be lunar age 29(sometimes 30 depending on birth month). This is why “Chinese gender chart age 28” is a common search — but the chart actually uses your lunar 28, which corresponds to roughly Western age 26-27.

Chinese New Year 2026 falls on February 17, 2026. So if you conceived in January or early February 2026, you may need to add an extra year to your lunar age.

Determining your lunar conception month

The Chinese lunar calendar months don't align exactly with Gregorian months. Lunar month boundaries shift each year. Roughly:

• Lunar month 1 (2026): Feb 17 – Mar 18
• Lunar month 2: Mar 19 – Apr 16
• Lunar month 3: Apr 17 – May 16
• Lunar month 4: May 17 – Jun 14
• ...and so on, each lunar month ~29-30 days

Because of these boundary shifts, manually converting your conception date to a lunar month is error-prone. A calculator handles this automatically.

How accurate is the Chinese gender chart?

Studies consistently show the Chinese gender chart performs at approximately 50% accuracy — statistically indistinguishable from a coin flip. A 2010 study published in the Canadian Medical Association Journal analysed 2.8 million births and found accuracy at 50.2%.

Why does it remain so popular despite this?

• Confirmation bias: people remember when it's right, forget when it's wrong
• 50/50 odds: half the people who use it find it “accurate” by pure chance
• Cultural tradition: a 700-year history makes it feel mystical

Using the Chinese gender chart for fun

The chart is genuinely fun for gender reveal parties, family games, and pregnancy keepsakes — just treat it as entertainment, not a basis for decisions. Many parents enjoy comparing the chart prediction against the eventual ultrasound result.
