Almost all African countries celebrate Christmas, as most countries have at least a small population if Christians, who live there. On the entire continent, there are approximately 350 million Christians in Africa.

However, as Christmas is not in wintertime, but instead mid-summer for African countries, they do not celebrate christmas with snow and sledges, but sunshine and blooming flowers.

Here are some statements on how Christmas is celebrated in Africa from several sources:

"In Congo in Africa, a group is designated just to prepare the annual Christmas pageant. In the Christmas morning, African people and groups of carolers walk around the village and sing Christmas carols. They then go to home to wear festive clothes and take love offerings for Jesus to the special service that is held at the house of worship. In the church, the birthday of Jesus is celebrated and people keep their gifts upon the raised platform near the Communion table. After the service, people invite friends to Christmas dinners arranged in front of their homes. "

"The Coptic Christians in Ethiopia and Egypt celebrate Christmas on the 25th of December in their calendar, which is the 7th of January for most of the rest of us. "

"Decorating shop fronts, mango trees, churches and homes is common throughout African Christian communities. You may see fake snow decorating store fronts in Nairobi, palm trees laden with candles in Ghana or oil palms loaded with bells in Liberia. "

I hope this information has helped you out.

In contrast to our western world, Christmas in Africa is not yet spoiled by commerce. Their emphasis is still more on religion, instead of gifts.
"The most common thing bought at Christmas is a new set of clothes to be worn to the church service. If gifts are exchanged in poorer communities they usually come in the form of school books, soap, cloth, candles and other practical goods."
