The circadian cycle refers to how our biological clock controls physical, mental and behavioral changes by responding to the lightness and darkness of the 24 hour cycle. This is controlled by a group of nerve cells within the brain known as the suprachiasmatic nucleus.

Each 24-hour cycle of and night is called a(n) zeitgebers!
Circadian can be translated as 'about' (circa), 'daily' (dian). Almost animals I can think of (plants, too) are responsive to the daily light/dark cycle of the sun, hence 'circadian'.
Circadian means day night cycles or it can mean anything else like that. Weekday and weekend cycles.
It is called the Circadian Rhythm.

circadian rhythm
Not exactly. Circadian rhythms are a subset of diurnal rhythms. Diurnal rhythms reoccur daily and can be circadian and non-circadian. Circadian rhythms can be set by the environment (entrainment), but are not dependent on environment stimulus for continuation (free-running) (ie. hormone secretion). Non-circadian rhythms are responsive to the environment, but still operate on a daily cycle (ie. the process of photosynthesis).
The biological cycle that is approximately 24 hours long is called the circadian rhythm. It regulates various biological processes such as sleep-wake cycles, hormone production, and body temperature fluctuations. Exposure to light is a key factor in synchronizing the circadian rhythm with the external environment.
