Poila Boishakh (Bengali: পয়লা বৈশাখ, or Bengali New Year Bengali: বাংলা নববর্ষ, Bangla Nôbobôrsho) is the first day of the Bengali calendar, celebrated on 14 April in Bangladesh and on 15 April in the Indian state of West Bengal by the Bengali people and also by minor Bengali communities in other Indian states, including Assam, Tripura, Jharkhand and Orrisa. It coincides with the New Year's days of numerous Southern Asian calendars like Tamil new year Puthandu. The traditional greeting for Bengali New Year is শুভ নববর্ষ "Shubhô Nôbobôrsho" which is literally "Happy New Year".
