Bai Tian

Bai Tian (白天) literally translates to "white sky" or "daylight" in Mandarin Chinese. It refers to the daytime hours, the period of time when the sun is above the horizon and there is natural light. It is the opposite of 黑夜 (hēi yè), which means "night." Bai Tian encompasses the hours from sunrise to sunset.

In common usage, Bai Tian denotes the time typically associated with activity, work, and wakefulness, as opposed to the night, which is usually associated with rest and sleep. The specific duration of Bai Tian varies depending on the time of year and the geographic location, being longer during the summer months and shorter during the winter months.

The term is widely used in everyday conversation, literature, and formal contexts to indicate the time of day.
