4am
Deep night hour
4am, also written 4 a.m. or 4 AM, designates four o'clock in the morning.
As a cultural reference point, 4am suggests either staying up very late or waking up unusually early—the deep night when most people are asleep.
It often carries connotations of insomnia, anxiety, late-night revelry, or the demands of work: I was still up at 4am worrying about the presentation.
In song titles and poetry, 4am typically evokes loneliness, introspection, or the liminal space between night and dawn.
