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).

circadian
Circadian rhythms are controlled by the hypothalamus in humans. Circadian rhythm refers to the body's biological clock that determines when a person should sleep, and it controls a variety of other body processes, as well.
The pineal gland secretes the hormone melatonin, which is involved in the control of circadian rhythms
No, the hypothalamus is not responsible for overall consciousness. Its responsibilities include releasing certain hormones, controlling body temperature, hunger, sleep, and circadian rhythms.

The hypothalamus is located below the thalamus and above the brain stem. Its functions are controlling body temperature, hunger, thirst, sleep, and circadian rhythms.

circadian
One of the most important functions of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland. The hypothalamus controls body temperature, hunger, important aspects of parenting and attachment behaviors, thirst, fatigue, sleep, and circadian rhythms.

Circadian rhythms are a living organisms day/night cycles, daylight interacting with body hormone chemistry.
