Artist Matt McCarthy created the observance in 2017 as a project for Make Your Own Holiday Day, also celebrated on March 26, to honor Leonard Nimoy's birthday and the Vulcan blessing from Star Trek.
Mark your calendars and beam down to March 26 for Live Long and Prosper Day! This special day is a celebration of the famous phrase from Star Trek, which has been around since 1966.

It's become an iconic phrase that's used by fans of the show as a way to wish each other well. So go ahead and join in on this intergalactic celebration – live long and prosper!
