Except in two cases where the PFM is one day earlier than this, namely:
*When (C+11G) is 0 modulo 30, PFM = [[April 18|18 April]] (not 19 April).
*When (C+11G) is 1 modulo 30, and G=12, PFM = [[17 April]] (not 18).
The Golden number (G) is the same for both Julian and Gregorian computations, but the Century term is constant (C = +3) in Julian computations:
