Bengali New Year (Bengali: নববর্ষ Nôbobôrsho) or Pôhela Boishakh (পহেলা বৈশাখ Pôhela Boishakh or পয়লা বৈশাখ Pôela Boishakh), occurring on the 14th April or 15th April, is the first day of the Bengali calendar, celebrated in both Bangladesh and the Indian state of West Bengal, and in Bengali communities in the other Indian states, including Assam, Tripura, Jharkhand and Orrisa. It coincides with the New Year's Days of numerous Southern Asian calendars. The traditional greeting for Bengali New Year is "Shubho Noboborsho" (Bengali: শুভ নববর্ষ).
In Bengali, Pohela stands for ‘first’ and Boishakh is first month of the Bengali calendar. Bengali New Year is referred to in Bengali as "New Year" (Bengali: নববর্ষ Noboborsho, from Sanskrit Nava(new)varṣa(year)) or "First of Boishakh" (Bengali: পহেলা বৈশাখ Pohela Boishakh or পয়লা বৈশাখ Pôhela Boishakh). Nobo means new and Borsho means year.
The Bengali calendar is loosely tied with the Hindu Vedic solar calendar, based on the Surya Siddhanta. As with many other variants of the Hindu solar calendar, the Bengali calendar commences in mid-April of the Gregorian year. The first day of the Bengali year therefore coincides with the mid-April new year in Mithila, Assam, Burma, Cambodia, Kerala, Manipur, Nepal, Odisha, Sri Lanka, Tamil Nadu and Thailand.
Origin of Bongabdo or Bangla Year is debated with primarily two hypothesis but historicity of none could be proved till date.
Mughal Emperor Jalaluddin Muhammad Akbar, the renowned grandson of Zahiruddin Muhammad Babur was the 3rd Mughal Emperor, introduced the Bengali Calendar. In regards of relatively easier tax collection, Akbar changed the practice of agricultural tax collection according to Hijri calendar and ordered an improvement of the calendar because the Hijri calendar, being a lunar calendar- did not agree with the harvest sessions and eventually the farmers faced severe difficulties in paying taxes out of season.
The regal astrologer of Emperor Akbar's reign, Aamir Fatehullah Siraji , was the one who in fact developed this calendar, after working out a research on the lunar Hijri and Solar calendar. The distinctive characteristic of the Bengali year was that, rather than being a lunar calendar, it was based on a union of the solar and lunar year. This was essentially a great promotion, as the solar and lunar years were formulated in very diverse systems.
Primarily this calendar was named as “Fasli San” and then Bongabdo or Bangla Year was launched on 10/11 March 1584, but was dated from 5 November 1556 or 963 Hijri. This was the day that Akbar defeated Himu in the clash of Panipat- 2 to ascend the throne.
Akbar-e-Azam’s ordered to resolve all dues on the last day of Choitro. The next day was the first day of the New Year (Bengali New Year), the day for a new opening; landlords used to allocate sweets among their tenants, and Businessmen would commence a “Halkhata” (new financial records book) and lock their old ones. Vendors used to provoke their consumers to allocate sweets and renew their business relationship with them. There were fairs and festivities allover and gradually Poyela Boishakh became a day of celebration.
The Bengali New Year begins at dawn, and the day is marked with singing, processions, and fairs. Traditionally, businesses start this day with a new ledger, clearing out the old.
People of Bangladesh enjoy National holiday on Pohela Boishakh. all over the country people can enjoy Fairs and festivals. Here singers sing traditional songs welcoming the New Year. Food vendors sell conventional foods and artisans sell traditional handicrafts. People also enjoy traditional jatra plays.
Village dwellers of Bangladesh traditionally clean their housed and people usually dress new clothes up. Like other festivals of the region, the day is also marked by visiting relatives, friends and neighbors. People prepare special dishes for their guests.
The rural festivities have now evolved to become vast events in the cities, especially the capital Dhaka.
In Dhaka and other large cities, the festivals begin with people gathering under a big tree.People also find any bank of a lake or river to witness the sunrise. Artists present songs to welcome the new year, particularly with Rabindranath Tagore's well known song " Esho, he Boishakh".
People from all spheres of life wear traditional Bengali dresses. Women are used to wearing traditional saris with their hair all bedecked in flowers. Likewise, men prefer to wear traditional Panjabis. A huge part of the festivities in Dhaka is a vivid procession organized by the students and teachers of Institute of Fine Arts, University of Dhaka.
Nowadays, Pohela Boishakh celebrations also observe a day of cultural unity without distinction between class, race and religious affiliations. Of the major holidays celebrated in Bangladesh and West Bengal, only Pôhela Boishakh comes without any preexisting expectations. Unlike Eid ul-Fitr & Durga Pujo, where dressing up in lavish clothes has become a norm, or Christmas where exchanging gifts has become an essential part of the holiday, Pôhela Boishakh is really about celebrating the simpler, rural roots of the Bengal. Eventually, more people can take part in the festivities together without the load of having to reveal one's class, religion, or financial capacity.
In Kolkata 
In Kolkata, Pohela Boishakh (and indeed the entire month of Boishakh) is considered to be an auspicious time for marriages. These days people wear new clothes and go about socialising.

Pohela Boishakh is the day for cultural programmes. Prayers are offered for the well-being and prosperity of the family. Young ladies clad in white saris with red borders and men clad in dhuti and kurta take part in the Probhat Pheri processions early in the morning to welcome the first day of the year. This day being auspicious, new businesses and new ventures are started. The Mahurat is performed, marking the beginning of new ventures.

Mantras are chanted and স্বস্তিক shostik ("Hindu swastika") are drawn on the accounting book by the priests. Long queues of devotees are seen in front of the Kalighat temple from late night. Devotees offer puja to receive the blessings of the almighty.
