Durga Ashtami 2026: Date, Tithi, Muhurta & Significance
In 2026, Durga Ashtami falls on Monday, 19 October 2026.
History & Mythology
Maha Ashtami is the burning heart of Durga Puja. On this day the Goddess is worshipped as Mahagauri, and in the Sandhi Kshana — the razor-thin junction of Ashtami and Navami lasting 48 minutes — she assumed the form of Chamunda to slay the demons Chanda and Munda, the moment commemorated in the Sandhi Puja with 108 lamps and 108 lotuses.
The Ashtami morning belongs to Kumari Puja, in which a young girl is worshipped as the living Goddess — a tradition given classical form at Belur Math by Swami Vivekananda in 1901. Devotees offer pushpanjali in new clothes, and in many traditions the day was once marked by bali (sacrifice), now most often rendered symbolically with a pumpkin or sugarcane. For Bengal, Assam and the east, Maha Ashtami is the single most attended morning of the Pujo; across the north it is the day of Kanjak, when nine girls are fed as the Navadurga.
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 with the Swiss Ephemeris, making dates accurate to the minute rather than relying on pre-printed almanacs.
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 two. This is why Diwali, Navratri and other festivals fall on different Gregorian dates each year.
What is Tithi in the Hindu calendar?
Tithi is the lunar day, 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 Shukla Paksha and 15 in the waning Krishna Paksha. Most festivals are tied to a specific Tithi, which is why their Gregorian dates shift each year.
What is Shubh Muhurta for festival rituals?
Shubh Muhurta is the auspicious time window for performing rituals, determined by combining Tithi, Nakshatra, Yoga, Vara and Choghadiya. AstroJanamPatrika computes the precise muhurta for each festival from your local sunrise, Tithi end times and auspicious Nakshatras.
What are 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 — Purnima for celebrations, Amavasya for ancestral rites (Pitru Tarpan).
