Plural of bedtime; the regular times when people, especially children, are expected or scheduled to go to sleep.
From bed + time (Old English 'tīm'). The compound word bedtime has been used since the 1600s to denote the designated hour for retiring to bed, with bedtimes emerging as a social concept with regular schedules.
Bedtimes are one of the first things humans use to regulate children's behavior—archaeological and historical evidence suggests that synchronized sleep times are actually very recent in human history and deeply tied to industrial work schedules.
