Mahalaya – October 10, 2026: The Beginning of the Durga Puja Season

Mahalaya falls on Sarva Pitru Amavasya, the final day of Pitru Paksha. It is traditionally associated with paying homage to ancestors through rituals such as tarpan and shraddha.

For Bengali families, Mahalaya also signals the beginning of the countdown to Durga Puja. The recitation of Chandi Path and the traditional early-morning broadcast of Mahishasura Mardini are strongly associated with this day. Mahalaya itself is not one of the five main days of Durga Puja. Rather, it marks the transition from the period dedicated to ancestors to Devi Paksha, the fortnight associated with the Goddess.

October 11: Devi Paksha Begins

The day after Mahalaya, Shukla Paksha Pratipada begins. In the broader Hindu calendar, this marks the start of Shardiya Navratri.

In 2026, Navratri begins on Sunday, October 11. Ghatasthapana and other Navratri observances begin during this period, although Bengali Durga Puja follows its own sequence of rituals and reaches its main celebrations later in the lunar fortnight. This is when the atmosphere gradually shifts from Pitru Paksha observances to preparations for Durga Puja.

October 11–15: Preparations Build Up

The days between Mahalaya and Shashthi are largely a preparation period for the main festivities. During this time, pandals are completed, idols are prepared and decorated, homes are cleaned, and families begin making arrangements for the upcoming Puja days. For devotees, these days also carry the anticipation of Maa Durga's arrival. The Goddess is traditionally understood as returning to her maternal home on Earth during Durga Puja.

October 16 – Shashthi:

Durga Puja preparations enter the main ritual phase with Shashthi observances, including Kalparambha, Bodhan and Bilva Nimantran. These rituals ceremonially invoke and welcome Maa Durga for the festivities ahead.

October 17 – Maha Saptami:

Maha Saptami marks the beginning of the major days of Durga Puja, with Nabapatrika Snan and Puja among the key traditions. Devotees begin the central celebrations with prayers and offerings to Maa Durga.

October 18 – Saptami:

Saptami celebrations continue with traditional worship, offerings and cultural festivities across Bengali communities. Pandals remain at the heart of the celebrations as devotees gather for darshan and Puja.

October 19 – Maha Ashtami:

Maha Ashtami is one of the most significant days of Durga Puja, marked by special prayers, offerings and, in many traditions, Kumari Puja. Sandhi Puja is observed at the transition between Ashtami and Navami.

October 20 – Maha Navami:

Maha Navami brings the final major day of Durga worship, with special Puja and Homa rituals performed in many communities. Devotees seek Maa Durga's blessings before the festival moves toward its emotional conclusion.

October 21 – Vijayadashami:

Vijayadashami marks Maa Durga's farewell, with Durga Visarjan observed after the Puja rituals. Bengali communities also celebrate Sindoor Khela and bid farewell with the hope of welcoming the Goddess again next year.

The Spiritual Journey From Mahalaya to Vijayadashami

The period from Mahalaya to Durga Puja is more than a countdown of dates. Mahalaya closes Pitru Paksha, Devi Paksha begins, preparations intensify, Maa Durga is invoked through Bodhan, and the main Puja unfolds through Saptami, Ashtami and Navami before concluding with Vijayadashami and Visarjan. For Bengali devotees, this progression transforms the anticipation of Mahalaya into the celebration of Durga Puja and finally into the emotional farewell of Asche Bochor Abar Hobe "the hope of welcoming Maa Durga again next year."
