Ecclesiastical full moon who began the experiments with independent computations held that the paschal full moon should never precede the equinox. The computational principles developed at Alexandria eventually became normative, but their reception was a centuries-long process during which Alexandrian Easter tables competed with other tables incorporating different arithmetical parameters. So for a period of several centuries the sequences of dates of the paschal full moon applied by different churches could show great differences (see Easter controversy).

A second possibility could be
