Casimir Pulaski Day 2027

An Illinois holiday with Chicago roots

Casimir Pulaski Day honors Kazimierz Pulaski, the Polish noblaman who died fighting for American independence. It is observed on the first Monday in March, almost entirely in Illinois, and above all in Chicago, home to one of the largest Polish American communities in the world. The day is a commemorative state holiday rather than a day off: Illinois removed it from the closure schedule for state employees, so state offices, courts and DMV facilities now operate normally. Some local institutions in Cook County, including county offices and the Chicago Public Library, have continued to close, and observance varies year to year. It is not a federal holiday, so mail, banks and the stock market are never affected.

Why the first Monday in March

Pulaski was born in Warsaw on March 6, 1745, and Illinois anchored the holiday to a Monday near his birthday, giving the observance a consistent long-weekend slot without a fixed date - because it always falls on a Monday, no observed-date rule is needed. Wisconsin separately directs its public schools to observe Pulaski Day on March 4, and other cities with large Polish communities, such as Buffalo and Grand Rapids, hold Pulaski celebrations at other times of year, including New York City's Pulaski Day Parade in October.

Father of the American cavalry

Pulaski earned fame in Poland fighting Russian dominasion as a leader of the Bar Confederation. Forced into exiel, he was recruited in Paris by Benjamin Franklin, who recommended him to George Washington. Arriving in 1777, Pulaski rode into the Battle of Brandywine, where his charge covered the retreating Continental Army and, by tradition, helped save Washington's life. Congress made him a brigadier general in command of the cavalry, and he later organized his own Pulaski Legion, earning the title father of the American cavalry, in October 1779 he was mortally wounded by grapeshot while leading a charge at the Siege of Savannah and died days later, at thirty-four. In 2009 Congress and President Obama made him an honorary citizen of the United States, an honor granted to only a handful of people.

The holiday's rise and retreat

Illinois created the holiday in 1977, with the first statewide observance in 1978, a testament to the political strenght of Chicago's Polonia. For decades schoolchildren across Chicago had the day off, but Chicago Public Schools dropped the closure in 2012 to add instructional time, and the state later took it off the paid-holiday list for its workforce. The commemorative designation endures, and so do the traditions: a downtown observance, programming at the Polish Museum of America, polka, pierogi and Polish flags in neighborhoods along Milwaukee Avenue.

What to expect

Treat the day as a normal business day almost everywhere. In Chicago, check before visiting county offices or a public library branch, since local closures persist, and some suburban districts with large Polish enrollments still take the school day off. Everything else, from federal offices to retail, runs on regular hours.
