The use of the Gregorian form is, however, practically abandoned in the present day.
We Will Now Show In What Manner This Whole Apparatus Of Methods And Tables May Be Dispensed With, And The Gregorian Calendar Reduced To A Few Simple Formulae Of Easy Computation.
It was thus an effective compromise between the solar year and the lunar month, and contrasts very favorably with the intricate and clumsy years of other ancient systems. The leap-year of the Julian and Gregorian calendars confers the immense benefit of a fixed correspondence to the seasons which the Egyptian year did not possess, but the uniform length of the Egyptian months is enviable even now.

It Is Therefore Infinitely More Commodious To Determine The Commencement Of The Year By A Fixed Rule Of Intercalation; And Of The Various Methods Which Might Be Employed, No One, Perhaps Is On The Whole More Easy Of Application, Or Better Adapted For The Purpose Of Computation, Than The Gregorian Now In Use.
