The bill establishes July 2 of each year as "1st Minnesota Day" to honor the 262 men of the 1st Minnesota Regiment who fought valiantly for the Union during the Civil War, specifically during the Battle of Gettysburg on that date in 1863. The legislation highlights the significant sacrifice made by these soldiers, with 215 of them killed in a crucial charge that helped secure the Union line. To commemorate this day, the governor is required to issue a proclamation each year, and schools are encouraged to educate students about the regiment's role in the Civil War, emphasizing the importance of their contribution to preserving freedom and democracy.

Additionally, the bill mandates that on 1st Minnesota Day, the commissioner of administration, in collaboration with the Minnesota Historical Society, will fly a replica of the 1st Minnesota Regimental flag on the North flag pole of the Minnesota State Capitol, replacing the POW/MIA flag for the day. This observance aims to ensure that the sacrifices of the 1st Minnesota Regiment are remembered and honored annually. The provisions of this bill will take effect the day following its final enactment.
