— what if you were… —

How old would you be
as an animal?

Aging at the pace of a dog, a cat or a tortoise, you would not be the same age at all. Just for fun.

About age in animal years

Curious how old you’d be as a dog, cat, tortoise or elephant? This animal-years calculator converts your human age into the equivalent age for eight animals, based on each species’ lifespan.

It’s a playful take on the famous “dog years” idea — and unlike the myth of multiplying by seven, it scales your age by each animal’s relative pace of life.

How old am I in dog years?

Enter your birth date and the calculator shows your equivalent age as a dog, cat, rabbit, horse, tortoise and more, based on their lifespans.

Is the “multiply by 7” rule accurate?

No — that’s a myth. This tool uses each species’ lifespan for a more meaningful (though still playful) comparison.
