The Ukrainian Christmas festivities start on Christmas Eve, which is celebrated on 6 January, following the Julian calendar. The Christmas celebrations end on 19 January, the date of "Jordan" or Epiphany.
Christmas Eve, or as it called 'Sviatyi Vechir' in Ukrainian ('Holy Evening') is filled with numerous customs and rituals. The customs include: decorating house and dinner table with special attributes (didukh, garlic, hay and others), performing koliadky ('carols') and so on. Each ritual has its own meaning and purpose, as such a few wisps of hay on the embroidered table cloth as a reminder of the manger in Bethlehem. One the most prominent customs of the night is a special supper, called Sviata Vecherya (Holy Supper).
Kutia (sweet grain pudding) is traditionally served at the Ukrainian Christmas dinner table. It is often the first dish in the traditional twelve-dish Christmas Eve supper (also known as Svyaty Vechir) and is rarely served at other times of the year.
At the end of the Sviata Vechera the family often sings Ukrainian Christmas carols. In many communities the ancient Ukrainian tradition of caroling is carried on by groups of young people and members of organizations and churches calling at homes and collecting donations. The Ukrainian song "Shchedryk" became the basis for the world famous Christmas carol, "Carol of the Bells". Another well-known carol is Boh predvičnyj narodivsja.
When the children see the first star in the eastern evening sky, symbolizing the trek of the Three Wise Men, the Sviata Vecherya may begin. In farming communities the head of the household now brings in a sheaf of wheat called the didukh which represents the importance of the ancient and rich wheat crops of Ukraine, the staff of life through the centuries. Didukh means literally "grandfather spirit" so it symbolizes the family's ancestors. In city homes a few stalks of golden wheat in a vase are often used to decorate the table.
