We only add things with a source. And unlike people Martians and Thanagarians (and even Humans) who age at a steady rate, Wonder Woman's longevity is not linear. She does not physically age when she's on Themyscira (at least beyond basic maturity, as she was sculpted from clay as a baby and left as the equivalent of a teenage girl). Prolonged stays on Man's world do make her age. She left Themyscira at the age of 16 and stayed for 10 years, and came back to Man's world around 2001. It's unclear if she spent all of those stays in Man's world nonstop, or if she went home now and then (she is on Themyscira during the events of Legacy), so a physical age is hard to gauge.

And it would be speculation anyway, and we don't do that.
