Vishwakarma Puja is a vibrant festival dedicated to Lord Vishwakarma, the celestial architect and divine engineer of the universe. He is credited with creating the palaces of the gods, Indra's Vajra, Krishna's Sudarshana Chakra, and many other divine weapons and cities.
Observed primarily on Kanya Sankranti, the day the Sun enters the zodiac sign of Virgo (around mid-September), the festival is especially important for artisans, craftsmen, carpenters, blacksmiths, mechanics, engineers, and factory workers.
In West Bengal, Bihar, Odisha, and Assam, the day is marked by colorful pandals in factories and workshops, where tools and machinery are decorated and worshipped. It emphasizes the dignity of labor and the spiritual value of honest craftsmanship.
