"Unity Day," it turns out, is a relatively recently created day set aside for people and corporate entities to be "... joined together against bullying, and united for kindness, acceptance, and inclusion."
That from:
https://en.wikipedia.org/wiki/unity_day_(united_states)which also goes on to describe the history of the day, and more about
it. Such as:
"Unity Day was started by PACER's National Bullying Prevention Center as a signature event of National Bullying Prevention Month. The call to action was to "Make it Orange and Make it End. Unite Against Bullying!" Participants were encouraged to wear orange to show their support for bullying prevention."
And a little bit more about
it:

As for the "unity" angle, maybe this adds a little bit to the spirit of togetherness that the day seems to be seeking:
