Baby Gender Planner

This application is based on the famous Chinese Birth Calendar.

This is FIRST app to predict the gender
on the exact day of month by converting solar calendar to lunar calendar.

Chinese Birth Calendar was initially created under
lunar calendar.

There will be a big difference if using solar calendar.

Under Lunar Calendar, mother is one year old
once born.
Age will be added upon celebration of each
spring festival.
So lunar age is one or two years older
than the solar age depending on calculation.

This application calculates ovulation period and
tells you when you will have better chance of
conception.

During regular 6 days ovulation period, first 3
days will have a better chance to have a girl.
And It is easy to have a boy during last 3 days.

period. Combining with Step 3, it will be used to
calculate the ovulation period to tell you when
you will have better chance of conception.

Step 3: Please select mother's cycle length.
Combining with Step 2, it will be used to calculate
