Juneteenth marks the official end of slavery in 1865. Most stores and restaurants are expected to be open normal hours.

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.

The holiday has been commemorated as America's Second Independence Day, and several companies may be updating their hours of operation in honor of the federal holiday. Juneteenth commemorates the end of slavery in the United States.
