Shani Jayanti, also known as Shanidev Jayanti, marks the birth anniversary of Lord Shani, the deity associated with justice, discipline, and karma. In 2025, Shani Jayanti falls on Tuesday, May 27, which is observed on the Amavasya Tithi (new moon day) of Jyeshtha month as per the Hindu calendar.
Significance of Shani Jayanti
Shani Dev is one of the Navagrahas (nine planetary deities) in Hindu astrology and is believed to influence human lives based on their deeds. He is the son of Lord Surya (Sun) and Goddess Chhaya and is the ruler of planet Saturn. Worshiping Shani Dev on this day is believed to reduce the ill effects of Shani Dosha, especially Sade Sati and Dhaiya, bringing relief from hardships and obstacles.
