Sharad Poornima is also known as Kojaagari Poornima or Kumar Poornima.It is celebrated on the full moon day of the Hindu lunar month of Ashvin (September - October).

It is also referred to as Rasa Purnima, or Sharath Purnima.
The "Sharad" in Sharad Poornima signifies the "Sharad ritu" (season) of the year. Basically a harvest festival, it also has religious significance. It is believed that on this night Goddess Lakshmi visits from place to place asking Kojagari (meaning "Who is awake") and bless those who are found awake. Therefore, people don't sleep this night and spend whole night singing, dancing and remembering god.
According to another belief sharad poornima is closely associated with Lord Krishna and Radha and Gopis. Lord Krishna began his Raas Leela with Radha and the gopis on the night of Sharad Poornima.
