Yes, I kid you not; this isn't an April Fool! Thursday 4 April is International Carrot Day.
Indeed you may well ask, "Why?" I did.
Well as it says here ...
Carrot Day was founded 2003 to spread knowledge about the carrot and its good attributes around the world. [It] is celebrated every year on April 4th and is the pinnacle for carrot lovers all around the world. It is the day when the carrot is celebrated through carrot parties and other carrot related festivities.
