not today. haha
If you have to be opposite on opposite day, that makes it a day, and then there was no opposite day. But that can't be true since you HAVE to be opposite, which means that you have to be normal even though there is an opposite day because you are supposed to be opposite on opposite day, which means that you act normal as if it was a normal day, because that is the opposite of opposite day. (This is a classic "liar's paradox". Since there is already an opposite day, you should have a normal day because that is the opposite of an opposite day. But then it is not an opposite day.)
a regular day
Yes, it is always true. If it was "opposite day", the actual meaning would be taken as 'it is opposite day'. If it was not opposite day, the sentence would be taken as read and would be correct. On Opposite Day : "It is not opposite day" = "It is opposite day" = True On Any Other Day: "It is not opposite day" = "It is not opposite day" = True If you said it WAS Opposite Day, it won't always be true.

The game "opposite day" is not an actual "day" but a semantics game where everyone says the opposite of what they mean. The amusement often comes from observing others who encounter the players and do not know a game is underway.
