Don’t celebrate this holiday today. Opposite Day is never celebrated on days other than this.
Opposite Day, also known as Opposites Day, is a word game where speech is modified so that meaning is inverted. Once Opposite Day is declared, statements mean the opposite of what they usually mean.
Usually, a person would say, “After this phrase is over, it will be officially opposite day,” and then Opposite Day will be officially started. Opposite Day can also be declared retroactively to indicate that the opposite meaning of what was said should be inferred. Opposite day games are usually played by schoolchildren.
In the sense that opposite day “excuses” untrue statements, it is similar to the notion that crossed fingers automatically nullify promises. Play has been compared to a children’s “philosophy course”, and the game has been used as an educational aid and suggested as preparation for “standardized testing”.
