Poila Boishakh is the Bengali New Year, the first day of the solar month of Boishakh, falling in mid-April. In West Bengal and Tripura it is kept with new clothes, sweets, cultural processions and the haal khata — the traders' ceremonial opening of fresh account books blessed before Ganesha and Lakshmi.
When: 1 Boishakh of the Bengali solar calendar — mid-April, at the Sun's entry into Mesha (Aries)
Where: West Bengal and Tripura, and among Bengalis everywhere; also the national new year of Bangladesh (as Pohela Boishakh)
Observance: New clothes, early bath, sweets and festive meals, prabhat pheri cultural processions, temple visits, and the haal khata blessing of new account books
Regional name: Poila Boishakh / Pohela Boishakh · Noboborsho (Bengali); the same solar day is Vaisakhi in Punjab and Vishu in Kerala
The first day of Boishakh
Poila Boishakh simply means 'the first of Boishakh', the opening day of the Bengali solar year, which begins when the Sun enters Mesha in mid-April. The same astronomical moment gives Punjab its Vaisakhi, Kerala its Vishu, Assam its Bohag Bihu and Tamil Nadu its Puthandu — a whole family of Indian solar new years. The Bengali calendar (Bangabda) as used today is generally traced by historians to revenue-calendar reforms of the Mughal period, layered over a much older solar tradition, though popular accounts also credit the ancient king Shashanka; the honest position is that its origins are composite. What is certain is the day's place in Bengali life: it is Noboborsho, the new year, when the greeting 'Shubho Noboborsho' passes between every friend and stranger, and when the year's ledger — commercial, personal and spiritual — is opened afresh.
How the day is celebrated
The day begins early: a bath, new or freshly washed clothes, and often a visit to a Kali or Shiva temple — long queues form at Kalighat in Kolkata and the Tripura Sundari temple in Tripura from before dawn. The most distinctive custom belongs to traders and shopkeepers: the haal khata, when the old year's accounts are closed and a new red-bound ledger is opened after being blessed in a short puja of Ganesha and Lakshmi, the lords of auspicious beginnings and prosperity. Customers are invited to the shop, offered sweets and cold drinks, and old dues are gently settled. Homes are decorated with alpona (rice-paste designs), and the table carries Bengali classics — from panta bhat and fish in traditional homes to elaborate sweets everywhere. Cultural life blooms too: prabhat pheri processions with Tagore songs, fairs (Boishakhi mela), poetry and music gatherings that mark the day as a festival of Bengali identity as much as of religion.
Noboborsho in Ottawa & Canada
For Bengali families in Canada, Poila Boishakh is one of the easiest festivals to keep meaningfully at home. Mid-April in Ottawa is early spring, and the day can open with a bath, new clothes, a lamp and flowers before the family shrine, and a short Ganesha–Lakshmi puja over a new diary or account book — students and professionals sometimes bless a new notebook or planner in the spirit of haal khata. A Bengali meal, phone and video calls to elders with 'Shubho Noboborsho', and Rabindra Sangeet in the house complete the mood. Bengali cultural associations in Ottawa, Toronto and Montreal commonly hold Noboborsho programmes of music, dance and food around the nearest weekend, and these are warm places for children to absorb the language and songs of the day. The exact Gregorian date shifts between 14 and 15 April; this site's Bengali calendar page shows it for any year.

Questions
Is Poila Boishakh a religious festival?
It is both cultural and religious. There is no single presiding deity, but the day traditionally begins with temple visits, and the haal khata custom includes a puja of Ganesha and Lakshmi for an auspicious and prosperous year. Its cultural side — music, processions, food, new clothes — is equally central.
Is it the same day as Vaisakhi and Vishu?
Essentially yes. All three mark the Sun's entry into Mesha (Aries) in mid-April, each through its own regional calendar and customs. Poila Boishakh is the Bengali expression of that shared Indian solar new year.
What is the haal khata?
It is the ceremonial opening of a new ledger — traditionally a red cloth-bound book — by traders on new year's day. The book is blessed before Ganesha and Lakshmi, customers are welcomed with sweets, and outstanding accounts of the old year are courteously closed.
Do West Bengal and Bangladesh celebrate on the same date?
The festival is the same, but Bangladesh follows a revised calendar that fixes Pohela Boishakh on 14 April, while the traditional calendar used in West Bengal and Tripura ties it to the astronomical sankranti, so it falls on 14 or 15 April depending on the year.
