Well, there are a few businesses that may be open on Christmas Day, such as gas stations, pharmacies, hospitals, and some restaurants. Many of these businesses are open to provide essential services or emergency care, but it's always a good idea to check with individual locations for specific hours and availability. Some businesses may also offer limited hours or services on Christmas Day. Additionally, some online retailers and delivery services may also be operating on Christmas Day to ensure that customers can still access their products and services.
