Put a number to it.

I think Christmas would be better if we could leave the birth of that fictitious bloke out of it. Then to add insult to injury we have to measure the passing of time to a point he was supposedly born.
Here's my idea: move the year forward by ten days so it starts at the solstice. Forget Jesus. Keep Santa - At least we all agree he doesn't exist - but in a fun and warm way.
Also replace Christmas cake with chocolate brownie.
And let's make year zero from when Jeremy Corbyn was born. Or Clarkson... I'm not fussy.
