Kojagiri Poornima or Ashwin Poornima is celebrated on the full moon day of Ashwin (September-October). As the rainy season passes, the sky becomes clear and the moon shines in the sky with full brightness. So, it is the celebration of this occasion, which is very traditional. It is also known as the Kaumudi, meaning moonlight.
Goddess Laxmi is worshipped on this day. People keep awake the whole
night singing songs or other entertaining things. Because Maharashtrians
believe that Goddess Laxmi moves around from place to place asking, 'Who
is awake?' (Kojagarti?). She shows her on those she finds awake. People
take only fluids like coconut water and milk. Milk masala, a readymade
combination of dry fruits and milk is taken on the day.
