Purple Up Day is a day of recognition and celebration to honor the service and sacrifice of military children. It began in 2017 as an effort to show appreciation for the families who serve alongside their active duty parents. The day is celebrated on the third Friday of May each year, and it has grown in popularity since its inception.
The color purple was chosen because it symbolizes all branches of the military, as it is a combination of red (for the Army), blue (for Navy, Air Force, Marines and Coast Guard), and white (for National Guard). On Purple Up Day, people are encouraged to wear purple clothing or accessories to show their support for military families. People can also participate by hosting events or attending community activities that honor military children.
