The First Council of Nicaea (325) established common Paschal observance by all Christians on the first Sunday after the first full moon on or after the vernal equinox.[18] Even if calculated on the basis of the Gregorian calendar, the date of that full moon sometimes differs from that of the astronomical first full moon after the March equinox.[19]

They wanted “first Sunday of Spring” but defined using their calendar, but that calendar doesn’t mesh perfectly with our calendar (and has leap months every few years), so converting to Gregorian makes it appear to move around.

Yep, that’s the idea
