Lakshmi Puja (Sanskrit: लक्ष्मी पूजा, IAST: Lakṣmī Pūjā), is a Hindu religious festival celebrated once in a year. It is celebrated on the Amavasya (new moon day) of Krishna Paksha (Dark fortnight). In the Vikram Samvat Hindu calendar it is celebrated in the month of Ashwin or Kartik. The puja is done on the third day of Tihar and is considered as the main event of Deepawali.
In Hinduism, Lakshmi is goddess of wealth and lord Vishnu's wife. It is believed that in this day she visits her followers and give them gifts and blessings. To welcome the Goddess, people clean their houses and make it bright with lights. They also prepare good food and sweets for offerings.
