The nineteenth day of June is designated as "Juneteenth National Freedom Day" to acknowledge the freedom, history, and culture that June 19, 1865, the day on which the last slaves in the United States were set free in Texas, has come to symbolize.

There is also National Freedom Day which is a United States observance on February 1 honoring the signing by Abraham Lincoln of a joint House and Senate resolution that later became the 13th Amendment to the U.S. Constitution. President Lincoln signed the Amendment outlawing slavery on February 1, 1865, although it was not ratified by the states until later.
