As Martin Luther King Jr. Day approaches, various cities and local governments are announcing closures and service modifications. Offices, including city and postal services, will generally be closed, with notable exceptions for some areas such as Jacksonville, where trash collection will proceed while mail services are suspended. Educational institutions will also observe the holiday, resulting in no school for students on this day. Residents are advised to check local listings for specific open and closed services, as well as celebrations or events recognizing the day.
