Circadian Rhythms have a cycle of
- 25 Hours.
- 24 Hours.
- 23 Hours.
Explanation from PART66Online
Left to run free without daylight and other time cues, the body's internal clock settles to a natural period of about 25 hours, which is why the rhythm has to be reset daily to the 24-hour day. The 24-hour figure is the entrained cycle, not the free-running circadian period taught here.

changes, the circadian rhythms will “free run” to a periodicity of about 25 hours
