Ascension Day in Denmark is celebrated as a public holiday, marking the event when Jesus Christ ascended to heaven following his resurrection, according to Christian belief. It is observed on the 40th day of Easter, which always falls on a Thursday. This holiday provides the Danes an extra day off, making it a long weekend if it is coupled with 'General Prayer Day', another holiday which usually falls near Ascension Day.

Denmark, being a predominantly Christian nation, observes Ascension Day with great reverence. Churches across the country hold special services on this day to commemorate the ascension of Christ. The holiday also provides a chance for families to spend time together. Many Danes use this day as an opportunity to enjoy outdoor activities such as picnics and barbecues if the weather permits.

Despite being a public holiday, not everyone in Denmark gets the day off. Some businesses remain open, while others may close or operate on restricted hours. However, most schools and other public institutions are typically closed on Ascension Day. Overall, the day offers a welcome break to the Danes, providing them with the opportunity to relax and to reflect upon their Christian heritage.
