On Monday, stock markets and non-essential federal offices will close in recognition of the country's newest federal holiday: Juneteenth.

Last year, President Joe Biden signed a bill that officially designated the 157-year-old holiday — which celebrates the emancipation of African-Americans from slavery in the U.S. — a federal holiday. "Great nations don't ignore their most painful moments," Biden said at the White House ceremony celebrating the bill's signing in June 2021. "They embrace them."
