Vishwakarma Puja is a Hindu festival honoring Lord Vishwakarma, the divine architect and craftsman of the universe, celebrated by engineers, artisans, mechanics, and factory workers who worship their tools, machinery, and workplaces for skill, safety, and prosperity. Observed annually around September 17th (Kanya Sankranti), it’s a day to appreciate craftsmanship, the dignity of labor, and seek blessings for smooth functioning of tools and success in their professions, often involving decorating workshops and abstaining from tool use as a mark of respect.
