Also the drift in ecclesiastical full moons calculated by the Gregorian method compared to the true full moons is affected less than one would expect, because the increase in the length of the day is almost exactly compensated for by the increase in the length of the month, as tidal braking transfers angular momentum of the rotation of the Earth to orbital angular momentum of the Moon.
The date for Easter shifts every year within the Gregorian Calendar.
If the Full Moon is on a Sunday, Easter is celebrated on the following Sunday.
Northern Hemisphere continents, like North America, begin to receive longer daylight because the planet tilts a bit more toward the sun.
