Answers to these and many more questions about Christmas in England can be found on the website of Woodlands Junior School in Tonbridge, Kent - along with an online advent calendar, Christmas teaching resources and jokes.
Nobody can accuse this school of being half-hearted about the annual celebration. It has a Christmas fair, Christmas lunch, Christmas performances and sends children to Hever Castle to sing carols.
While other schools are replacing the three kings with the seven dwarves, Woodlands is sticking with a traditional nativity play.
The jokes on its site, displayed among falling snowflakes and accompanied by a festive jingle, are sent in by children from all over the world. Here are just three from a vast collection:
What do you get if you eat Christmas decorations? Tinselitis.
What is brown and sneaks around the kitchen? Mince spies.
What did the pack of Walkers say to the Skips? Merry Crispmas!
Groan-worthy stuff. But ideal for Christmas cracker-makers.
