The Juneteenth holiday needs some historical corrections.
The holiday focuses on racist (whites are bad for not freeing Texas slaves for two years) propaganda. While in reality it marks the end of the US civil war when Texas .
Other dates that deserve celebrating include
July 2, 1777, Vermont became the first colony to abolish slavery [Reuters, 2007]
March 22, When the US congress enacted the Slave Trade Act of 1794. This prohibited US ships from carrying slaves. It was the first law restricting slave trade in the world. [Wikipedia, ND]
March 2, When the US congress enacted Act Prohibiting Importation of Slaves of 1807 [Wikipedia,ND]. The US was one of the first countries to prohibit slave trade even beating the United Kingdoms, Abolition of the Slave Trade Act, 1807 on 25 March 1807 [Wikipedia,ND].

April 9th 1665, Lee surrenders at Appomattox Court house. "The last the final skirmish of the Civil War occurred on May 12 and 13 at the Battle of Palmito Ranch" Union victory [History.com,2020]. Note, these are the dates that that slavery in Texas was legally abolished.
"Juneteenth (short for “June Nineteenth”) marks the day when federal troops arrived in Galveston, Texas in 1865 to take control of the state and ensure that all enslaved people be freed".
