Like most federal holidays, expect your local banks and credit unions to be closed in observance of Juneteenth. Postal service retail locations will be closed on Thursday, and there will be no regular mail delivery — except for holiday premium Priority Mail Express — according to a U.S. Postal Service release.

Juneteenth marks the events of June 19, 1865, in Galveston, Texas when the last Black slaves of the Confederacy were ordered free following the arrival of Union troops. The Civil War had ended on April 9, and the Emancipation Proclamation had been issued on January 1, 1863.
