Poila Boishakh marks the first day of the initial month of Boishakh of the Bengali calendar. The Poila Baishakh commemoration usually happens on the 14th of April every year but in India, it can also be celebrated a day later.
People from the Bengali community celebrate Poila Baisakh by greeting each other ‘Shubho Nobobarsho’. They seek blessings from God and their elders. Several dishes are prepared to mark the day, houses are decked up and people wear new clothes. A harvest calendar called Fasholi Shan was then created and some people believe that this was the advent of the Bengali calendar.
