What are the origins as to when & why April 1st is associated with fools?

It was a Myan thing.

I seem to remember hearing that it had something to do with the calendar changing – the 31st was added into March, so people who’d forgotten about the change walked around thinking that it was April 1st when it was really the newly-created March 31st. Those people were known as “April Fools”.

Whether that story has any truth? I doubt it. It’s just what I remember being told or having read long long ago.

@MrItty Sounds like typical reverse mythology.

@Storms I agree. Like I said, I doubt the veracity of the theory.

We are, zodiacally speaking, in a period of youthful vigour, pride and egotism, and much idocy. April fool’s day would be the perfect antidote and grounding mechanism for such behaviour.
