Because this Victorian cycle differed from the Alexandrian cycle in the dates of some of the Paschal Full Moons, and because it tried to respect the Roman custom of fixing Easter to the Sunday in the week of the 16th to the 22nd of the lunar month (rather than the 15th to the 21st as at Alexandria), by providing alternative "Latin" and "Greek" dates in some years, occasional differences in the date of Easter as fixed by Alexandrian rules continued. The Alexandrian rules were adopted in the West following the tables of Dionysius Exiguus in 525. From this time, therefore, all discrepancies between Alexandria and Rome as to the correct date for Easter cease, as both churches were using identical tables.
