Devipaksha In Bengal, Odisha, Jharkhand, Assam
The entire year is a collection of 24 pakshas (fortnights/lunar phases). Among these, twelve are Krishna Paksha (waning moon/dark fortnight) and the remaining twelve are Shukla Paksha (waxing moon/bright fortnight). Devi Paksha (Fortnight of the Goddess) is the fifteen-day period that runs from the day after Mahalaya, i.e., the Pratipad (first day) of the Shukla Paksha, until Kojagiri Purnima (full moon). This is what Bengalis wait for all year because during this paksha, Goddess Durga is worshipped. Durga Puja, the greatest festival of the Bengalis, is held during this fortnight.
Mahalaya is the junction of Pitri Paksha (Fortnight of the Ancestors) and Devi Paksha. It is commonly believed that Devi Paksha begins from Mahalaya. However, that is not the case. Pitri Paksha's tenure is until Mahalaya. The Amavasya (new moon) Tithi (lunar day) at the end of Pitri Paksha is named Mahalaya. As long as the Amavasya exists, it is Pitri Paksha, and as soon as the Amavasya Tithi passes and the Pratipad begins, Devi Paksha starts.
Devi Paksha is the time for worshipping the Goddess.
From the first day of Devi Paksha, the worship of one of the nine forms of the Goddess begins. Pratipad is the first day of Sharad Navratri. On Pratipada, Pratipadadi Kalparambha, meaning the awakening (Bodhan) of the Goddess, takes place.
With the beginning of Devi Paksha, there is a tradition in many homes to start reciting the Chandi Path (recitation of the Devi Mahatmya).
It was during this fortnight that the Goddess defeated Mahishasura and saved the three worlds.
Overall, the fifteen days of Devi Paksha are a time for worshipping the Mother. The world celebrates the worship of the Mother Goddess (Matri Shakti). Goddess Durga is worshipped from Shashti (sixth day) until Navami (ninth day), after which Devi Paksha concludes with the worship of Goddess Lakshmi on Kojagiri Purnima. This paksha is named Devi Paksha because of the worship of Devi, the Mother Goddess.
