Muhurat trading is a special one-hour trading session on the day of Diwali, marking the beginning of the Hindu financial year. It is considered an auspicious time as traders view it as a sign of prosperity for the year ahead.

Its history traces back to ancient Indian trading communities, where traders would perform puja (worship) of their account books and ledgers on this auspicious day. This tradition eventually evolved into the modern practice of Muhurat trading in the stock market, which takes place on the New Year of Vikram Samvat, a Hindu calendar in India.
