The United States has a new federal holiday commemorating the end of slavery, Juneteenth, after President Biden signed the bill into law today at the White House.  Senator Tina Smith, among those there:

“Juneteenth celebrates freedom and it celebrates the emancipation of people who were enslaved in our country.”

Juneteenth commemorates June 19, 1865, when Union soldiers brought the news of freedom to enslaved Black people in Galveston, Texas about two-and-a-half years after President Lincoln in the Emancipation Proclamation declared slaves in the Southern states to be free.
