Durga Puja creates a positive and fun-filled atmosphere all around with the sound of 'dhak' (drums), chants and devotional songs. It is the festival which depicts the victory of good over evil.

Goddess Durga had killed the demon king Mahisasur and thus the heaven and earth rejoice on the victory.

It is believed that mother Durga is invited to visit her maternal home and the invocation given to her is by 'Mahalaya', i.e, chanting mantras and singing devotional songs – "Jaago tumi Jaago...Jaago Durga.."

Goddess Durga then visits home for five days and Bengalis celebrate, worship, and enjoy the five days of Durga Puja – Shashti, Maha Saptami, Maha Ashtami, Maha Navami and Vijayadashami.

The Puja ends by immersing Maa Durga's idol in water and by chanting 'asche bochor abar hobe' (It will happen again next year).

This year the auspicious festival will commence on 30 September. The unique part about this year's Durga Puja is that the ninth and 10th day – Maha Navami and Dashami – fall on the same day.
