Christmas Eve, known as 'Štedrý deň' in Slovakia, is the most significant day of Christmas celebrations in the country. The day is steeped in traditional customs and rituals that begin with a period of fasting.

The history of Christmas Eve in Slovakia can be traced back to ancient times when it was believed that supernatural powers showed themselves on this day and animals could speak with human voices.

A typical Slovak Christmas Eve starts with dinner preparations. The main dish is usually "Kapustnica" - a thick cabbage soup with mushrooms and sausages, followed by fried carp and potato salad. Many families also prepare "Oplátky" - Christmas wafers which are eaten with honey and garlic for good health.

Before dinner, the table is set with all the dishes as it's believed that everything should be served at once. Also, an extra plate is set for an unexpected guest or for a departed family member's spirit.

After dinner, families gather around the Christmas tree to sing carols and exchange gifts. The tradition of gift-giving was originally associated with St. Nicholas but has since been taken over by "Ježiško" (Baby Jesus).

In many households, a bundle of straw is spread under the tablecloth representing Jesus' manger and is also a reminder of Slovakia's agricultural past. Another interesting tradition involves cutting apples crosswise - if the core forms a star shape, it means everyone will be healthy and happy in the coming year.

At midnight, many Slovaks attend Midnight Mass to celebrate Jesus' birth. Despite modern influences, these age-old traditions continue to add charm to Christmas Eve celebrations in Slovakia.
