Narali Purnima or Rakhi Pournima takes place in Maharasthra & Kerala.It is also called as Coconut Day festival.The Hindu festival of Narali Purnima or the Coconut festival is celebrated with great fervor and in a jubilant manner by the fishermen and the fishing community in Maharashtra on the full moon day of Shravan.

Narial (naral in Marathi) which means coconuts, are offered to the sea god Varuna, to seek his blessings for a fruitful fishing season, hence the name Narali Purnima comes into the picture. It is believed that an offering of gold coconut to the sea will bring in a lot of luck but since it is a very costly affair many do not follow it.Dancing and singing are an integral part of this festival. The traditional food includes sweet coconut rice which is savored with curry.
The reason for offering no other fruit but the coconut is because coconut has long been regarded as an auspicious offering Gods in all Hindu festivals. This is because every part of the tree – leaves, bark, coconut itself is extremely useful to man. Thus, this offering of coconut is believed to appease the Sea god for a safe journey ahead in the waters.

Normally, sisters tie Rakhi on the wrist of their brothers. They tie Rakhi and perform their Aarti. Brothers give the word of protection to their sisters in return and also give them some gifts.
