Gecko age calculator

Leopard geckos age very differently to humans — they're considered juveniles for their first year, reach full maturity around 18 months, and can live 15–20 years. Enter your gecko's age to see where they sit on the human scale.

How it works

Leopard geckos don't age at a constant ratio to humans — they develop very fast in their first year (think childhood compressed into months) and then slow significantly. The conversion accounts for these phases rather than using a simple multiplier.
