6 months
Time: 182.6 days; definition.
A month is defined here as one twelfth of a Julian year (30.4375 days). Calendar months vary.
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.

How to read the visual
The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.
- We use 120 days for the lifespan of a red blood cell; the recorded range is 100 days–130 days.
- The lifespan of a red blood cell: This is a representative comparison value; individual specimens or conditions can vary.
