Answer

In Jain Dharma, the soul is understood to enter the womb at the moment of conception, when the sperm and ovum unite. Jain texts describe this conception as garbha. So it is not usually given as a specific month. ( jainqq.org)

Explanation

For Tirthankaras, this conception event is called Chyavana Kalyanak, meaning the soul leaves the previous body and is conceived in the mother’s womb. ( jainfoundation.in)

Spiritual Understanding

This teaches that life is sacred from the very beginning of conception, so Jain Dharma emphasizes deep respect, purity, and care during pregnancy. ( jainqq.org)

Takeaway

In Jain belief, it is not “in which month,” but “at conception.” ( jainqq.org)
