Mahalaya Amavasya
History & Mythology
According to the Mahabharata, when the great warrior Karna died in the Kurukshetra battle, his soul reached the realm of Yama. There, Karna found only gold and jewels offered as food—because, despite his legendary generosity during life, he had never donated food to his ancestors during the Shraddha (ancestral rites). He was granted fifteen days to return to earth and feed the poor and offer Tarpan (water offerings) for his forebears. These fifteen days are Pitru Paksha, and their closing day—Mahalaya Amavasya—is the most sacred for ancestral rites.
Descendants stand in rivers and ponds at dawn, offering water mixed with sesame seeds, calling the names of their ancestors and their gotra, releasing the water in a sacred gesture of nourishment. The belief is that even one sincere drop of water offered on this day feeds and liberates the souls of the departed.
In Bengal and Assam, this dark moon simultaneously marks the dramatic awakening of Durga from her cosmic sleep. The legendary radio broadcast "Mahishasura Mardini"—first aired by All India Radio in 1932 at dawn—has been broadcast continuously for nearly a century. The sound of Birendra Krishna Bhadra's sonorous voice intoning Sanskrit hymns at dawn on Mahalaya has become the most evocative signal of Durga Puja for millions—a voice so associated with the goddess that it has become a tradition in itself.
Frequently Asked Questions
How are Hindu festival dates calculated?
Hindu festival dates are calculated using the Panchang — the Vedic almanac based on Tithi (lunar day), Nakshatra (Moon's asterism), and other astronomical factors. Most festivals fall on specific Tithis in particular lunar months. AstroJanamPatrika calculates these using Swiss Ephemeris, making dates accurate to the minute rather than relying on pre-printed almanacs.
What is Tithi in the Hindu calendar?
Tithi is the lunar day in the Hindu calendar, determined by the angular distance between the Moon and Sun in multiples of 12°. There are 30 Tithis in a lunar month — 15 in the waxing phase (Shukla Paksha) and 15 in the waning phase (Krishna Paksha). Most Hindu festivals are tied to specific Tithis, which is why their Gregorian calendar dates change each year.
Why do Hindu festival dates change every year?
Hindu festivals follow the lunisolar calendar, not the Gregorian solar calendar. Because the lunar year is about 11 days shorter than the solar year, festivals drift earlier each year — and an intercalary month (Adhika Masa) is added roughly every 2–3 years to realign the calendar with the solar year. This is why Diwali, Navratri, and other festivals fall on different Gregorian dates each year.
What is Shubh Muhurta for festival rituals?
Shubh Muhurta is the auspicious time window for performing festival rituals, determined by combining Tithi, Nakshatra, Yoga, Vara, and Choghadiya. AstroJanamPatrika calculates the precise muhurta for each festival based on local sunrise, Tithi end times, and auspicious Nakshatras.
What is Purnima and Amavasya?
Purnima is the full moon day (15th Tithi of Shukla Paksha) when Moon and Sun are 180° apart. Amavasya is the new moon day when they are conjunct. Both are highly significant in the Hindu calendar — Purnima for celebrations and Amavasya for ancestor rituals (Pitru Tarpan). Festivals like Holi, Guru Purnima, and Sharad Purnima all fall on Purnima.
