Diyas (lamps) are lit in homes during Diwali. Lighting of lamps is done on Amavasya (new moon day) of the Hindu month of Ashwin, which is usually the month of October or November every year. It is in remembrance of the return of Lord Ram, Mata Sita, Lakshman and Hanuman to Ayodhya after completing the exile of fourteen years. Symbolically, the lights remind us the need for self realization and inner enlightenment.
Happy And Safe Diwali To Everyone!
