Akshaya Tritiya, also called Akha Teej, falls on the third lunar day (Tritiya) of the bright fortnight of the month of Vaishakha. The word akshaya means "that which never diminishes," and the day carries a powerful promise: anything begun or invested on this date, wealth, knowledge, relationships, charitable acts, will grow without end. It is considered one of the most inherently auspicious days in the Hindu calendar, sat alongside Yugadi and Vijayadashami as a Sarvashubha (universally auspicious) day.
Mythology runs deep on this day. It is believed to be the birthday of Lord Parashurama, the sixth avatar of Vishnu. It is the day the Treta Yuga began. The Mahabharata tells us that Lord Krishna gifted Draupadi the Akshaya Patra, the inexhaustible vessel, on this very tithi, ensuring her household would never go hungry. The Ganges is also said to have descended to earth on Akshaya Tritiya, and the great sage Veda Vyasa is believed to have begun dictating the Mahabharata to Ganesha on this day.
Because the day is rooted in the idea of abundance that multiplies, it has become deeply associated with buying gold, starting new businesses, signing agreements, and solemnising weddings, all acts whose rewards are thought to compound endlessly when begun under this tithi's grace.
