For Russian Orthodox Christians, this day is extremely Holy.
Russian people stop eating any product that comes from an animal with the exception of seafood.
On the night of Christmas eve, Russian people go to Church for the Christmas Mass, and then go home. Not much celebrating takes place, rather off to bed, and then up in the morning and straight to church for the Christmas day Liturgy. After church people will go to the home of one relative so that the family can all be together. Here, the family gives gifts, and have Christmas lunch - the main meal of Christmas. Russians decorate their homes with the Christmas tree as does the west, and often put pine leaves on their front doors, and in the house.
