Is Trader Joe's open on Juneteenth?
Trader Joe's closes on a handful of days each year.

Every so often, the U.S. government decrees a new federal holiday. The most recent addition is Juneteenth, also known as Juneteenth Independence Day, commemorating the end of slavery in the U.S.
On Juneteenth, which became a named holiday in 2021, banks and federal offices, including U.S. Post Office locations, are closed. The stock market is also closed.
