The Sunday of an ordinal ISO week "n" is also the "n"th Sunday of the year, except in A/AG, B/BA and C/CB years where it is the "n"+1st Sunday, so both major proposals put Easter on the 15th Sunday of the year except either in common years starting on Monday (G), where 8 April, i.e. the second Sunday in April, is the 14th Sunday of the year, or in leap years starting on Sunday (AG), where 15 April, i.e. the Sunday after the second Saturday in April, is the 16th Sunday of the year.
