Name syllable
The Moon’s nakshatra and pada at the moment of birth (Lahiri), and the traditional first syllable for that pada from the Avakahada chakra — in Latin letters and Devanagari, with all four padas of the star shown, and a warning when the birth time is close to a pada boundary.
Due date
Naegele’s rule from the first day of the last period, adjusted for cycle length, with weeks pregnant today, the 37–42-week window, and the tithi and nakshatra on the due date.
In the Android app
Outside India, the free Android app also has the traditional Chinese lunar gender chart and a classical Vedic rule — offered for fun only: they are about as accurate as a coin toss and must never inform any decision about a pregnancy. They are not on this website, and not in the version of the app distributed in India, where pre-natal sex determination is unlawful.
