Juneteenth; designate as a legal holiday in the State of Mississippi.

HB 537 amends Mississippi's state code to add June 19th (Juneteenth) as an official legal holiday, alongside existing holidays like New Year's Day and Independence Day. This change directly affects all state government offices, employees, and public schools, which would close on Juneteenth as a paid holiday. The bill updates Section 3-3-7 of the Mississippi Code of 1972 to include Juneteenth in the official list of legal holidays, specifying it as "the nineteenth day of June (Juneteenth)." Unlike other designated days (e.g., Elvis Presley Day), Juneteenth is recognized as a legal holiday requiring state operations to close, not merely a day of observation.
