Why is juneteenth and the 4th of july recognized and celebrated differently?

Juneteenth, also known as juneteenth independence day[1] or freedom day, is an american holiday that commemorates the june 19, 1865, announcement of the abolition of slavery in texas, and more generally the emancipation of enslaved african americans throughout the former confederate states of america, outside native american lands. texas was the most remote of the slave states, and the emancipation proclamation of january 1, 1863, was not enforced there until after the confederacy collapsed. the name of the observance is a portmanteau of "june" and "nineteenth", the date of its celebration.[2][3] juneteenth is recognized as a state holiday or special day of observance in 46 of the 50 states.
