Juneteenth is this Thursday, and if you need to mail a package or conduct a banking transaction you may want to consider planning ahead.

That is because most national banks and the United States Postal Service will be closed on Thursday, June 19 in observance of the federal holiday.

Juneteenth, known as American's Second Independence Day, has been commemorated as a federally-recognized holiday since 2021, providing millions of Americans with a paid day off and the opportunity to commemorate the end of slavery.

The holiday commemorates the day when Maj. Gen. Gordon Granger arrived in Galveston Bay, Texas in 1865 with 2,000 Union troops to proclaim that more than 250,000 enslaved Black people in the state were free – two and a half years after President Abraham Lincoln signed the Emancipation Proclamation on Jan. 1, 1863.

Here's what you need to know about banks, post offices and shipping services, and whether or not they'll be open on Juneteenth.

Juneteenth is always celebrated on June 19. This year, the date falls on a Thursday.

All post offices will be closed for retail transactions and there will be no regular residential or business mail deliveries on Thursday, June 19, according to the U.S. Postal Service's website.
