Ahoi Ashtami is a Hindu festival celebrated about 8 days before Diwali on Krishna Paksha Ashtami.
According to Purnimant calendar followed in North India, it falls during the month of Kartik and according to Amanta calendar followed in Gujarat, Maharashtra and other southern states, it falls during the month of Ashvin.
However, it is just the name of the month which differs and the fasting of Ahoi Ashtami is done on the same day.

The fasting and puja on Ahoi Ashtami are dedicated to Mata Ahoi or Goddess Ahoi.
She is worshiped by mothers for the well-being and long life of their children.
This day is also known as Ahoi Aathe because fasting for Ahoi Ashtami is done during Ashtami Tithi which is the eighth day of the lunar month.
Ahoi Mata is none other than Goddess Parvati.
