With your help we can perfect the calendar...
Would you like a 100% accurate, yet simple and cost-free
method for predicting or planning baby gender? Today the
Chinese Gender Calendar is probably as close as you can
get, but still the accuracy is not 100%.
We are currently collecting gender prediction data in order
to increase the accuracy of the calendar with statistical
methods. If you have tested the calendar on births that
have taken place in your family or among friends, we would
appreciate if you could share the results with us. The
data will hopefully result in an improved calendar, which
later will be presented on this site for you and everyone
else to enjoy!
It is important that the data is accurate, so please provide
prediction results only from births where the
circumstances are well known. Also make sure to carefully
follow the step-by-step calculation procedure that we
provide under the 'Usage' tab.
The survey form lets you submit up to 10 results at a time.
For each birth, simply select mother's age at conception,
month of conception and result of prediction (successful
or unsuccessful) in the drop-downlists. Before hitting the
submit button, please make a final check that all the data
were entered correctly.
