Mahalaya, marking the beginning of the countdown to Durga Puja, will be observed across Bangladesh on Saturday.
The occasion marks the end of Pitri Paksha and the beginning of Devi Paksha in the Hindu calendar.
Devotees pay homage to their ancestors through religious rituals, while the day also signifies the arrival of Goddess Durga.
Mahalaya traditionally heralds the start of preparations for Durga Puja, the largest religious festival of the Hindu community.
