I want to know the answer to the following question:
What is the name given to the celebrated date of 23 April 1775 in New Haven?
All the background I'm provided with is that "On 23 April 1775, which is still celebrated in New Haven as Powder House Day, the Second Company, Governor's Foot Guard, of New Haven entered the struggle against the governing British parliament.". Is that enough to answer the question?
Answer: yes
