Wonderful Weirdos Day

Today is Wonderful Weirdos Day.

According to National Today, “Wonderful Weirdos Day is celebrated across America on September 9.” ¹

Why is it celebrated during an ordinary unit of time such as a day. Isn’t that boring and totally not weird? Wouldn’t it be more appropriate to designate it as Wonderful Weirdos Nychthemeron? ^{2, 3}
