In Hindu mythology, the full moon day is called Purnima (pronounced "poorna-ma"). This Sanskrit word literally means "full" or "complete," and refers to the full moon phase.

Each Purnima is associated with a specific deity and has its own unique significance and rituals. For example:

* Shravan Purnima: Dedicated to Lord Shiva and associated with the legend of the churning of the ocean.

* Kartik Purnima: Dedicated to Lord Vishnu and celebrates the victory of good over evil.

* Magha Purnima: Celebrates the birth of the Hindu deity, Lord Shiva.

* Phalguna Purnima: Dedicated to Lord Krishna and marks the end of the Holi festival.

Purnima is a significant time for prayer, meditation, and spiritual practices in Hinduism. It is believed to be a time when the divine energy is at its peak, making it auspicious for religious rituals and activities.
