Designates several new state holidays

HB 1959 designates three annual observances in Missouri: June as "Immigrant Heritage Month" to celebrate immigrant contributions, October 2nd as "Wrongful Conviction Day" to raise awareness about wrongful convictions, and December 1st as "Freeman Bosley, Sr. Day" honoring a retired St. Louis politician. The bill creates no new legal requirements or funding but formally names these dates for public recognition. It directly affects all Missouri residents by encouraging participation in related events. The designation applies statewide with no specific restrictions or targeted groups.
