Calculating Easter using the Jewish Calendar in One Step

Stephen P. Morse, San Francisco




The Paschal Full Moon (PFM) was originally defined as the first full moon on or after March 21.
Today it is defined by an Ecclesiastical table-driven algorithm that approximates the above.
Easter is defined as the first Sunday following the Paschal Full Moon.

This site calculates an approximation to the PFM and Easter dates from the new moons in the Jewish calendar.
It also calculates the PFM and Easter dates using the Ecclesiastical algorithm.
The intent is to see how the two results compare.
