Designates the tenth day of March of each year as a public holiday, to be known as Harriet Tubman day

This bill adds March 10th as an official public holiday in New York State, named "Harriet Tubman Day." It directly affects state employees, public institutions, and organizations that observe public holidays under existing law. The key provision amends the General Construction Law to include "the tenth day of March, known as Harriet Tubman day" in the list of designated public holidays. The change takes effect January 1st following enactment and does not alter existing holiday observances or create new government programs.
