The biggest religious festival of the Hindu community in Bangladesh is the festival of Durga Puja. Hindus participate in this festival with great devotion. Durga Puja is an old festival but it is difficult to say with any degree of certainty exactly how old it is. 

Apart from the Hindus, there are also two other minority religions communities in Bangladesh, viz., the Christians and the Buddhists, who observe religious festivals of their own. 

Celebrations of Pahela Baisakh started from Emperor Akbar's reign. It was customary to clear up all the year's dues on the last day of Chaitra (the twelfth month of the Bengali calendar). On the following day, or the first day of the new year, landlords would entertain their tenants with sweets. On this occasion fairs used to be organized there. 

Amor Ekushey February is a historic day for the Bengali nation. On that day five valiant sons of this country laid down their lives to win recognition for Bangla as a State language. 

Muharram or the 'sacred month' is the first month of the Islamic or Hijri calendar. The tenth day of Muharram is called Ashura. Imam Husain (R) the grandson of the Holy Prophet (SM) was killed on this day at the hands of the troops of Yazid. 

Dubla Rash Mela is not only a big fair for Bagerhat, it is undoubtedly one of the biggest fairs in the country.

Moheshkhali is an island under Cox's Bazar district not very far from the mainland. There, the Adinath temple at the top of Mainak hillock is a place of worship for Hindu devotees.

From the 1st day of the Bengali month of Mag - 7, a fair is held in Golakandail village of Rupganj upazila under Narayanganj district for seven days under a big banyan tree. Nobody knows the origin of the fair but it has continued for ages and is full of fun and festivity.

Every year on the 8th day of the Iunar month falls in the Bengali month of Chaitra, thousands of Hindu devotees from home and abroad assemble on the banks of the old Brahmaputra river for Astami snan, a ritual bath in the river.

The fair is also known as Baruni fair. In fact, there is a ghat in the village Ghoshbila under Alamdanga upazila of Chuadanga district which is considered a holy place by the Hindus as a legend says that the goddess Ganga once appeared here.
