Every year, about a week before Durga Puja begins, many Bengali homes wake up before sunrise to the same familiar voice on the radio. That is the signal that Mahalaya has arrived. If you have been wondering what is Mahalaya, why it matters and how it connects to Durga Puja, this guide explains it in simple words.
This year Mahalaya fell on Saturday, 10 October 2026, so it has just passed. The article is written as an evergreen explainer, so you can keep it for next year too. Note: dates are provisional. Verify with a local panchang (तिथियाँ स्थानीय पंचांग से मिलाएँ). Durga Puja dates here follow the Kolkata / West Bengal reckoning.
What is Mahalaya?
Mahalaya is the new-moon day (Amavasya) of the Hindu month of Ashwin. It is also called Sarva Pitru Amavasya. Many people explain the word as maha (great) plus alaya (abode), and the day is seen as the moment when the preparation for the goddess’s arrival begins.
It marks the transition between two fortnights: Pitru Paksha, the fortnight of ancestors, and Devi Paksha, the fortnight of the goddess. In 2026, Mahalaya was on Saturday 10 October, Sharad Navratri began on Sunday 11 October and, by the Kolkata reckoning, Maha Shashthi falls on Saturday 17 October.
From Pitru Paksha to Devi Paksha
Pitru Paksha is the roughly fifteen-day period when families remember departed ancestors through shraddha rites, offerings of water and food, and charity. Many traditions treat these days as a quiet, reflective time rather than a time for new ventures.
Mahalaya closes that fortnight. The next day the bright half of the month begins, and with it Devi Paksha, the period of festivals dedicated to the goddess. So the day carries two feelings at once: gratitude towards ancestors and the start of Shakti worship.
Tarpan: offering water to ancestors
In Bengal, the morning of Mahalaya is the most popular day for tarpan. Many people go to a river ghat, and the Ganga ghats of Kolkata are especially busy at dawn. The steps are usually simple:
- Take a bath at dawn and wear clean clothes. Some people fast until the rite is complete.
- Remember the departed family members by name and offer water mixed with black sesame, barley and flowers.
- Give food, clothes or money to those in need, as far as you are able.
- Follow your family priest’s guidance, because customs differ from family to family.
Chandipath and Mahishasuramardini
The sound of Mahalaya for most Bengalis is Chandipath, the recitation of verses from the Devi Mahatmya (Chandi), which praise the goddess as the destroyer of evil. The best-known version is the radio programme Mahishasuramardini, which blends recitation and devotional songs and is associated with the voice of Birendra Krishna Bhadra. Many families still switch it on around 4:00 AM, and today it is available on television and online too.
Whether you are in Kolkata or far away, listening to the programme on Mahalaya morning is a cultural ritual as much as a religious one. If you want to read about the goddess’s names and hymns in Hindi, see Durga Saptashati mantra and Durga Ashtakam on our site.
Chakshu Daan: giving eyes to the idol
Around Mahalaya, image makers traditionally paint the eyes of Durga idols, a ritual called Chakshu Daan. It symbolises the awakening of the image before the formal rites that follow on Shashthi. Many pandals share photographs of this moment on social media each year.
How Mahalaya connects to Durga Puja
Think of Mahalaya as the prologue and Durga Puja as the story. According to popular belief, the goddess leaves her marital home on Mount Kailash and comes to her parental home on earth for a few days, accompanied by Lakshmi, Saraswati, Ganesha and Kartikeya. Durga Puja then runs from Shashthi to Dashami.
Here are the 2026 dates by the Kolkata / West Bengal reckoning:
- Maha Shashthi: Saturday 17 October
- Maha Saptami: Sunday 18 October
- Maha Ashtami: Monday 19 October (Sandhi Puja around 10:27 to 11:15 AM, Ashtami ends 10:51 AM)
- Maha Navami: Tuesday 20 October
- Bijoya Dashami: Wednesday 21 October, with Sindoor Khela in the evening and then Bisorjon (immersion)
All-India Dussehra / Vijayadashami is on Tuesday 20 October 2026. Read more in our guides to Durga Puja and Dussehra. For the Ashtami ritual, see Sandhi Puja Explained.
