Aadi Krithigai is a significant festival dedicated to Lord Murugan, the son of Lord Shiva and Goddess Parvati, who is worshipped as the God of war, wisdom, and bravery. This festival is observed on the Krithigai Nakshatra day in the Tamil month of Aadi (July–August), and it holds particular importance in Tamil Nadu.

Aadi Krithigai marks the day when Lord Murugan is believed to have been born from the divine sparks emanating from Lord Shiva’s third eye, and it is a celebration of Murugan’s divine energy and his role as the protector of righteousness. On this day, devotees celebrate Lord Murugan’s power and seek his blessings for victory over obstacles, strength, and mental clarity.

The puja begins with early morning rituals, where devotees take a holy bath, offer fruits, flowers, betel leaves, and coconuts to Lord Murugan. Panchamritam (a mixture of milk, yogurt, honey, ghee, and sugar) is used for abhishekam to the idol of Lord Murugan, and the chanting of Murugan Ashtakshara Mantra, Subramanya Bhujangam, and Kandar Anubhoothi is an essential part of the puja.

Special rituals include the lighting of lamps and offering of kavadi (a symbolic offering, often in the form of a decorated structure carried by devotees). In some regions, devotees also observe a fast or partial fast on Aadi Krithigai. The temple and surrounding areas are often decorated with lights and flowers to mark the occasion.

Aadi Krithigai Puja is believed to bring victory, protection, and blessings from Lord Murugan, helping devotees overcome challenges in their personal and professional lives. It is a day that emphasizes devotion, sacrifice, and spiritual growth.
