Discover the unpredictable origins and etymologies of our Christmas customs this festive season.

For something that happens every year of our lives, we really don't know much about Christmas.

We don't know that the date we celebrate was chosen by a madman, or that Christmas, etymologically speaking, means "Go away, Christ". We're oblivious to the fact that the advent calendar was actually invented by a Munich housewife to stop her children pestering her for a Christmas countdown. And we would never have guessed that the invention of crackers was merely a way of popularising sweet wrappers.

Luckily, like a gift from Santa himself, Mark Forsyth is here to unwrap this fundamentally funny gallimaufry of traditions and oddities, making it all finally make sense - in his wonderfully entertaining wordy way.
