Jivitputrika Vrat, also known as Jiwit Putra or Jitiya fasting, is observed on the eighth day in the waning phase (Ashtami of Krishna Paksha) of the Ashwin Month.
Jitiya Fast is observed for the well being of the sons by mothers. After early morning bath and prayers, mothers start the fast and do not take any food during the whole day.
The rituals associated with the Vrat vary from region to region but the purpose is the same.
