Lakshmi Puja on Purnima tithi in the month of Ashwin is known as Kojagari Puja.

The word Kojagari is derived from the phrase ‘Ko jagorti’ or Who is awake? According to legends, Goddess Lakshmi descends on the Earth on the full moon day of the Ashwin month and is believed to walk around asking ‘who is awake?’ Those who answer her get her divine blessings.
