The Chinese Pregnancy Calendar, also referred to as the Chinese Conception Calendar, is based on a fascinating historic calendar presently stored in the Beijing Institute of Science. The gender calendar is said to have been buried a thousand years ago in a royal tomb.

How to Use the Chinese Pregnancy Gender Calendar
Using the Chinese gender calendar (located at the bottom of the page) can be a bit tricky. Basically, you need to know two important pieces of information:
- The month of conception
- Your lunar age of conception
What Is My Month of Conception?
This one is pretty easy and self explanatory. If you're a bit fuzzy on the month your baby was conceived, just use our pregnancy calculator to figure that out.
What Is My Lunar Age of Conception?
This is the more complicated one. Basically, it means you want to find out your age on the Chinese calendar (which is a lunar based calendar) at the month of conception.
We have a handy calculator to help you quickly determine your lunar age of conception. You can learn more about how your lunar age is determined by reading the somewhat confusing details below the calculator.
Once you've figured out the month the baby was conceived and your lunar age of conception, scroll down to the bottom of the page and look at the full Chinese gender calendar.
Those with a lunar age of conception of 21 shouldn't get their hopes too high if they want a boy! (of course, take the whole Chinese gender calendar with a grain of salt).
Determine Your Lunar Age of Conception & Gender of Your Child
Enter your age when the baby was conceived (this is your regular age, not the Chinese lunar age). Then, enter the month when the baby was conceived. Hit "Calculate!", then the page will refresh & you'll have to scroll back down to see the results.
How Your Lunar Age of Conception Is Determined
According to the Chinese lunar system, when you were born, you were 1 year old. Then, after each Chinese New Year, you add one more year (regardless of when your birth date actually is). This means that if you were born shortly before midnight on the evening before the Chinese New Year, you would be 2 years old the next morning.
The difference between the Chinese lunar calendar and our Western Gregorian calendar is approximately two months. The Chinese New Year typically is sometime in the month of February, but, each year, it falls on a different date.
To figure out your Chinese lunar age when your baby was conceived, you will need to do the following:
- If the time your baby was conceived falls between the Chinese New Year and your birth date, it will be your age at the time of conception + 2 years.
- If the time your baby was conceived falls after your birth date (and before the next Chinese New Year), it will be your age at the time of conception + 1 year.
