Yes, Christmas Eve is a federal holiday in the United States. Many people take the day off work or have reduced work hours on Christmas Eve, so that they can spend time with family and friends and prepare for Christmas. Businesses and government offices are usually closed on Christmas Eve, and many schools and universities are also closed. In addition to being a federal holiday, Christmas Eve is also a religious holiday for Christians who celebrate the birth of Jesus Christ. Many churches hold special services and events on Christmas Eve to commemorate the holiday.
