“from 12 o'clock at night to 6 o'clock in the morning” 这个时间段又被称作“midnight to dawn”或“the wee hours”。这种表达方式来自英语中描述时间的习惯，即以12点钟为一天的起点，分别称之为“midnight”和“noon”。
例句：
The party went on until the wee hours of the morning. (聚会一直持续到清晨的很晚。)
I always have trouble sleeping during the hours between midnight and dawn. (我总是在午夜至黎明的时间段里睡不着。)
The city is most quiet during the hours between midnight and dawn. (城市在午夜至黎明的时间段里最安静。)
