Venus solar day
A Venus solar day is the interval between two successive sunrises at the same location on Venus, which is much longer than an Earth day.
Also known as: day on Venus, Venus day

A little perspective
Venus solar day vs Red-cell lifespan: duration comparison
The lifespan of a red blood cell is about 1.03 times the solar day of a Venus solar day.
ELAPSED TIME
A Venus solar day is the interval between two successive sunrises at the same location on Venus, which is much longer than an Earth day.
Red-cell lifespan is the average time a human red blood cell remains in circulation before being removed from the bloodstream.
Measurements, assumptions & sources +
Venus solar day
Solar day: 116.8 days; approximate; range 116.7 days–116.9 days.
One Venus solar day lasts about 116.75 Earth days, approximately 10.09 million seconds. This differs from Venus’s longer retrograde sidereal rotation period.
The marked solar day is calibrated. Unmeasured illustration details are representative.
Red-cell lifespan
Typical circulating lifespan: 120 days; representative; range 100 days–130 days.
A typical human red blood cell circulates for about 120 days, or 10.368 million seconds, before removal. Lifespan varies with cell condition and health; this is not a transit time.

Why this measurement?
Why we use 116.8 days
We compare the solar day of a Venus solar day. This is an estimate; check the notes for its rounding and uncertainty. The recorded range is 116.7 days to 116.9 days.
One Venus solar day lasts about 116.75 Earth days, approximately 10.09 million seconds. This differs from Venus’s longer retrograde sidereal rotation period.
