The Leaping Pope

Pope Gregory the 13th is
Best known for a timely decree -
Gregorian calendar biz,
So less confusion there might be.
Fifteen eighty two was the year,
Ten days got dropped to start the math
Of when and how leap days would steer.
The rules followed a tricky path
For calendar on time to seek.
Three thousand years from now will need
An extra day to take a tweak.
But none of us should fret, indeed.

So would it be a leap to say
Pope Gregory turned time his way!
