"Shubho Nobo Borsho!" Clinton said in her message to the Bengali community.
"As you celebrate this special day, know that the United States stands with all Bengalis everywhere as we work for a more peaceful and prosperous future."
"On behalf of President (Barack) Obama and the people of the United States, I send my best wishes to all Bengali-speaking people around the world as you celebrate Poila Boishakh in the coming days. I wish all Bengalis prosperity and happiness in this new year of promise and possibility," Clinton said.
The Secretary of the State also said it is an opportunity to honour the rich history of Bengali culture with music, drama and traditional foods. She believed Bengali artists, scientists, politicians and entrepreneurs have positively influenced American culture.
"Bengali-Americans will join their fellow Bengali family and friends to celebrate the many accomplishments of the Bengali people," she added.
