Well the whole Christmas celebration in my culture is quite a long story, but I have an interesting Pre-Christmas celebration for you.
The habit of celebrating pre-Christmas or little Christmas during the first weeks of December. Pre-Christmas with food and drinks, mostly with mulled wine, is celebrated among colleagues in offices and other places.
This Pre-Christmas tradition basically means you celebrate Christmas before with everyone else besides your family and relatives, so you could have more time and full focus on your close ones on the actual day of Christmas.
It's a very good habit, there's love for everyone on those days.
Happy Holidays!
