In Iran, where the Wise Men are believed to have lived, Christians long have marked the season by fasting from animal products.
In Mexico, the main Christmas celebrations involve processions re-enacting Joseph and Mary's search for a place to stay in Bethlehem.
Christians in India often decorate mango or banana trees at Christmas.
