About the Circadian Rhythms Clock Sun Moon black outline icon
A round clock with hour ticks and hands sits at the center, wrapped by a curved double-arrow loop that turns continuously. A small sun sits on the daylight side and a crescent moon on the night side, and the whole scene is held in a circular badge frame. It communicates the body clock, sleep-wake cycles and daily routine for sleep tracker apps, health and wellness dashboards, shift-work scheduling tools, biology slides and medical infographics.
The rotating arrows break at both ends of the clock so the sun and moon read clearly instead of blending into the ring. Hour marks are short dashes that hold shape when scaled. It works next to alarm clock, sleep and biological clock icons. Use at 48px or above so the sun rays stay distinct.
This is the black outline version of the circadian rhythms clock sun moon icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
