About Casimir Pulaski Day

Casimir Pulaski Day is an Illinois commemorative holiday observed on the first Monday in March.

Illinois law directs the Governor to issue a proclamation before the holiday and designate official events honoring Casimir Pulaski and his contribution to American independence.

Why Casimir Pulaski Day matters

The observance commemorates Casimir Pulaski, a Polish-born military figure remembered for service during the American Revolutionary War.

The current Illinois statute uses the wording “birthday of Casimir Pulaski” for the holiday. This guide reports that statutory wording without using it to resolve separate historical debates about Pulaski’s exact birth date.

History of Casimir Pulaski Day

Illinois’s current State Commemorative Dates Act places the Casimir Pulaski holiday on the first Monday in March.

The code identifies Public Act 87-272 as the source of the current codified section and separately lists the former Casimir Pulaski Holiday Act among acts repealed during recodification.

The 2026 Illinois proclamation states that the first Monday in March has been designated Casimir Pulaski Day since 1977. The exact first observed edition is not established by the reviewed primary sources.
