Diwali or Deepawali is one of the most celebrated and joyful festivals of the year. As per Ramayana the Hindu epic, it is that, on this Lord Rama, Goddess Sita, Hanuman, and Lakshmana returned to their home at Ayodhya after spending 14 years in forests. Apart from this belief, it has been also said that Goddess Lakshmi was born on that day during Samudra Manthan (churning of the cosmic ocean). This is because Goddess Lakshmi is the most significant deity who worshipped during Diwali Puja.
According to the Hindu calendar, the festival of Deepawali is observed on Amavasya that comes on the 15th day of Kartik month, every year. On this day, Lord Ganesha and Goddess Lakshmi are worshipped in Deepawali Puja that is also called ‘Lakshmi Ganesh Pujan’.
However, this year the festival of Diwali will be on the 4th of November across the country. The tithi of ‘Amavasya’ begins from 06:03 on November 04, 2021, and will ends on 02:44 on November 05, 2021.
In Maharashtra, the festival of Diwali begins before the day of Govatsa Dwadashi. And, in Gujarat, the Diwali festivities start two days before from Agyaras and culminates on the day of Labh Panchami.
