How Old Is The Leap Year Frog?

The Leap Year Frog Who hops down his mountain into Holiville quadrennially is a staple of the town, but how old is he? The Gregorian Calendar was made 443 years ago, so would that be his age or would he be a measly 110 years old. If the latter is true that would make him one of the youngest residents in the town, I guess we will have to ask him next time he leaps on down.
