Rishi Panchami Dinam
It is celebrated on the next day of Diwali. The literal meaning of this day is the day of solidarity of five rishis (sages). This day is celebrated by the followers who believe that this day is not the birthday of Lord Vishwakarma, as according to their belief, a god is immortal and hence cannot die or take birth. According to the myth, this is the day when the five sons of Lord Vishwakarma came together and invoked their father the day is celebrated in commemoration of that event. As it is celebrated according to the Hindu lunisolar calendar, it is celebrated on different dates every year.
Between the two days of Vishwakarma Puja celebration, this is the day which is more popular among the Hindus who celebrate it with pomp and show. It is celebrated as the birthday of Lord Vishwakarma and is observed on 17th September every year. This day is also commemorated as the day when Vishwakarma people crafted and gifted the plough to humanity. The plough gradually gave birth to civilization as the wanderers became cultivators and later these cultivators settled down to form society and civilization. So this day is celebrated to commemorate Lord Vishwakarma as well as to honor the early Vishwakarma people.
