Although rooted in religious tradition, St. Patrick's Day celebrations have evolved into a largely secular event, marked by parades, parties, and Irish-themed festivities. What started as a feast day in Ireland has evolved into one of the largest celebrations in the United States.

St. Patrick's Day is celebrated annually on March 17 in honor of the patron saint of Ireland. While not a federal or state holiday in Michigan, many cities hold parades and events to celebrate Irish heritage.
