I want to know the answer to the following question:
As one of the oldest and largest traditions, how long have the city been celebrating Saint Patrick's Day?
All the background I'm provided with is that "New Haven's Saint Patrick's Day parade, which began in 1842, is New England's oldest St. Patty's Day parade and draws the largest crowds of any one-day spectator event in Connecticut.". Is that enough to answer the question?
Answer: yes
