Most Hindu festivals move with the lunar calendar, but this one doesn't. Vishwakarma Puja follows the solar calendar and falls on Kanya Sankranti, the day the sun enters the zodiac sign of Kanya, which keeps it landing between 16 and 18 September each year, on the last day of the Hindu month of Bhadra. In 2026, that means Thursday, 17 September, with the Kanya Sankranti moment arriving around 7:58 AM and the puja muhurat running from 7:15 AM to 4:15 PM. The festival is observed in Nepal, where it carries a full government holiday, and in India, where it is marked as a restricted rather than national holiday.
Vishvakarma is described in the Rigveda as the architect and personification of divine creativity, credited with building the city of Dvaraka for Krishna and the palace of Indraprastha for the Pandavas, and with forging weapons such as Vishnu's Sudarshana Chakra and Shiva's trishula. He is also said to have authored the Sthapatya Veda, the science of mechanics and architecture, which is why he is regarded as the patron deity of craftsmen rather than a god invoked for wealth or protection.
The puja plays out on shop floors and in workshops rather than temples. Artisans, mechanics, welders, smiths, engineers, architects and factory workers set up shrines among their own equipment, praying for safe working conditions and for machines to keep running smoothly through the year ahead. Many see their own workmanship as an extension of Vishvakarma's shakti, or creative power.
The rituals follow a rough sequence that varies by workplace: the space is cleaned, often the night before; an image or idol of Vishvakarma is placed on a decorated platform; tools and machinery are gathered nearby and marked with kumkum and turmeric tilak; offerings of flowers, fruit and sweets are made; the mantra "Om Vishwakarmaye Namah" is recited, sometimes alongside a longer Puranic version; and the day closes with aarti, an optional havan fire ritual, and prasada shared among the workers.
The custom has carried over into workplaces that look nothing like a traditional workshop IT offices bless laptops and servers, logistics firms bless their truck fleets, hospitals bless diagnostic equipment. Visitors are unlikely to find a dedicated tourist event, since this is a workplace observance rather than a public spectacle, but those passing factories, garages or small businesses on the day should expect to see swept floors, marigold garlands on machinery, and framed images of Vishvakarma set up for the puja.
