There isn't a word in English. In Norwegian it's a døgn.
Each 24-hour cycle of day and night is called a "day."
"At the third hour of the night" refers to 3 o'clock in the morning. It is commonly used to specify a time during the middle of the night.
The pattern of fluctuations in bodily processes that occur regularly each day is called circadian rhythms. These biological rhythms follow a roughly 24-hour cycle and influence various physiological functions, including sleep-wake cycles, hormone release, and metabolism. Circadian rhythms are regulated by internal biological clocks and can be influenced by external factors such as light and temperature.
Interphase is the longest phase in the cell cycle lasting 18 of the 20 hour cycle. In mitotic cell division cycle,the longest phase is G1 phase which lasts for 10 hours,S phase is for 9 hours,G2 phase for 4 hours and shortest phase is M phase which lasts for 1 hour.
A 60th of an hour is called a minute.
Each 24-hour cycle of day and night is called a "day."
Each 24-hour cycle of day and night is called a day. It consists of one period of sunlight (daytime) and one period of darkness (nighttime).

The roughly 24-hour cycle that your body goes through is called the circadian rhythm. It regulates various biological processes, such as sleep-wake cycles, hormone release, and body temperature fluctuations. Disruptions to this rhythm can impact overall health and well-being.
It is called the Circadian Rhythm.
Night and day.
The polar areas during the solstice periods.
In the context of a day-night cycle, a night typically refers to the period of darkness between sunset and sunrise. Therefore, the fourth night would encompass the fourth period of darkness following the previous three nights. If each night is considered to be a full 24-hour day cycle, then the fourth night would consist of the nighttime hours of the fourth day and the subsequent daytime hours of the fifth day.
The side of the Earth facing away from the Sun has shadow, or is called night. Depending on the latitude and season the duration is half the 24 hour diurnal cycle, on average 12 hours.
The apparent size of the moon's illuminated portion is constantly shrinking during the two weeks after Full Moon, leading up to New Moon ... not only daily, but continuously, even hour by hour. This portion of the moon's cycle is called the "waning phases".
The cycle of night and day is primarily governed by the Earth's rotation on its axis, a phenomenon known as diurnal motion. This cycle doesn't have a specific scientific name like other processes might, but it is fundamentally related to the concept of "circadian rhythms," which are biological processes that follow a roughly 24-hour cycle influenced by light and darkness.
Each 15-minute period is called a quarter of an hour because an hour is divided into four equal parts, and each part represents one-quarter of the total time. Since there are 60 minutes in an hour, dividing that by four gives you 15 minutes. Thus, each 15-minute segment is one-quarter, or "quarter," of the hour.
