For which holiday is a gun salute NOT typically given?

A gun salute is a ceremonial practice that is typically reserved for specific holidays, significant state events, and the memorialization of honored individuals such as fallen service members or presidents. In the context of U.S. military customs, holidays such as Christmas, Thanksgiving, and President's Day, each of which holds historical significance, are occasions for honoring the nation and its leaders, where a gun salute might be performed as part of the celebrations or commemorative events.

Labor Day, however, is primarily observed as a celebration of the American labor movement and the contributions of workers throughout the nation. It does not have the same level of historical or ceremonial significance associated with military honors, making it the least likely to warrant a gun salute among the given options. Thus, it stands out as a holiday where such military honors are not typically rendered, in contrast to the other holidays listed, which have strong ties to military commemoration or national pride.
