US government offices close for Juneteenth, as do any private businesses that participate.
As for whether state government employees get a paid day off – that depends on whether state authorities mark Juneteenth as a state holiday, a day of observance or something in between. It is a varied picture.
Similarly, celebrations and traditions differ across the US. In some states there are parades, festivals and block parties where people gather to share food and play games.
As well as public readings and singing, picnics and church services, in some states rodeos, contests, concerts and parades are also organised.
Food also plays an important part, with barbecues being one of the most popular ways of marking the day with family and friends.
Many people choose to shop at black-owned businesses or eat at black-owned restaurants.
Others elect to attend solemn or reflective events that call attention to ongoing racial inequality.
