In 2021, Juneteenth was recognized as a US federal holiday to commemorate the emancipation of enslaved African-Americans and honor Black culture. It has been celebrated annually on June 19 in various parts of the United States since 1865. If you are already using a holiday calendar in MS Project, below are the dates to add in for Juneteenth.

Beware that the default holiday calendar in Project is empty; it does not include any legal holidays. You are; therefore, forced to construct or import one on your own. Without the use of a holiday calendar, projects can fall behind by up to two weeks per year.

As I’ve shared previously, a complete, pre-populated holiday calendar through 2050 is available at MSProjectHolidayCalendars.com. It includes every national holiday in the US or Canada, including Juneteenth, and, I hope, it will save you from the time-consuming and error-prone process of researching and manually inserting the holidays into y our own calendar.
