A bare tree stands
with roots on both ends
in December days.
~Kiran Bantawa, "Bare Trees"

How did it get so late so soon?
It's night before it's afternoon.
December is here before it's June.
My goodness how the time has flewn.
How did it get so late so soon?
~Dr. Seuss

Christmas begins about the first of December with an office party and ends when you finally realize what you spent, around April fifteenth of the next year. ~P.J. O'Rourke, Modern Manners: An Etiquette Book for Rude People, 1983

I heard a bird sing
In the dark of December,
A magical thing,
And sweet to remember:
"We are nearer to spring
Than we were in September."
~Oliver Herford, "Hope," in The Century Magazine, January 1914
