As usual with most of your writings, you are sadly misinformed.

Leibnitz independently developed many ideas of calculus as early as
1674, and used well-developed methods of calculus, expressed in his
own, superior notation, in correspondence with other mathematicians
starting around 1677.

Newton's Principia Mathematica was published in 1687.
