Why does dc celebrate emancipation day but most states do not?

Washington, D.C. celebrates Emancipation Day on April 16 to commemorate the signing of the Compensated Emancipation Act in 1862, which freed enslaved people in the District. This event is significant as it represents a local acknowledgment of the end of slavery, distinct from the national observance of Juneteenth. Most states do not celebrate Emancipation Day because they observe Juneteenth, which marks the announcement of slavery's end in Texas on June 19, 1865, reflecting a broader and more widely recognized moment in the history of emancipation across the United States. Each state's historical context and legislative choices influence their recognition of these dates.
