For a long time Opposite Day has been a holiday that existed only in the minds of the people who declared it. Once someone says it’s opposite day, everything done after that means the opposite of what it usually means and you do the opposite of what you would normally do. Why it’s now associated with January 25th is unclear, but you can still feel free to celebrate it on any day you’d like. Always remember to declare its "Opposite Day!"
Here are a few fun ideas on celebrating Opposite Day.
Swap Breakfast and Dinner - Eat Dinner in the morning and eat Breakfast for dinner!
Wear clothes backwards or wear your jacket under your shirt
Silly talk on Opposite Day is fun and easy. Just say the opposite of what you would normally say.
Say Good Night in the morning and Good Morning before bed
No means Yes and Yes means No
Right means Left and Left means Right
Up means Down and Down means Up
So don't have fun and cry when you are miserable not celebrating opposite day.
