What term is used for the time to sleep, marking the end of the day?

The term used for the time to sleep, marking the end of the day in a military context, is "Taps." This is a ceremonial piece of music played during the evening at military installations, signaling the end of the day's activities and encouraging soldiers to retire for the night. Traditionally, Taps is played to indicate that soldiers should cease their activities, reflect on the day, and prepare for rest. It is steeped in history and carries significant meaning within military culture, emphasizing discipline and order as part of daily life.

While other terms like Tattoo and Reveille are also significant in military routines, they refer to different times or events. Tattoo typically denotes a time for last call to their posts before the evening ends, while Reveille marks the beginning of the day when service members are awakened. Evening Muster generally refers to a gathering of personnel at a designated time for roll call or inspection, not necessarily indicating the end of the day. Thus, Taps is specifically associated with the conclusion of daily activities and the transition to night, solidifying its role in the framework of military life.
