Juneteenth became a federal holiday just three years ago, so there’s still a lot of confusion about its impact on people’s day-to-day lives.

If you’re planning to get any business done with your state or local government, you can pretty much rule that out, but when it comes to private businesses, it’s more of a mixed picture. Many companies, including Zillow, Nike and Lyft, give workers the day off, while others (like Amazon) have not, only encouraging workers to not make meetings today.

Looking to make sense of what is and isn’t open? We’ve got answers.

What is Juneteenth?

On June 19, 1865, two months after the Civil War officially ended, the last Black slaves of the Confederacy were ordered free when Union troops arrived in Galveston, Texas. The day became known as Juneteenth and, for a long time, it was only observed in Texas.

Over the years, though, the day of remembrance began to spread. It came to national prominence following the 2020 unrest that followed the murder of George Floyd by a Minneapolis police officer.
