(International) Skeptics Day?

Do you believe in Skeptics Day?
It may be today -- I’m not sure.
It’s on the thirteenth, so they say,
October, January. More?
Any time it falls on a Friday?
Such limits I do not care for.
Some also add Election Day --
Believing it is quite a chore.

Can they prove whatever they say
Or must they still show you more?
Where are the facts for you to weigh
And the theories yet to explore?
It is not proof the other way
To ask why of the common lores.
No answer yet does not hold sway
Even when the belief is yours.
