Frederick’s Epitaph

Frederick died after a long and productive life of 87 years, but this epitaph was written on his headstone:

Frederick lived a good long life,
He loved his children and his wife,

He was honest, kind and deserved nothing but praise,
Even if he only had twenty-one birthdays.

How is this possible?

He was born on February 29th in a leap year. Consequently, in his 87 years, he only witnessed twenty-one of his actual birthdays. The other years there was no February 29th.
