The only missing detail which is important for full understanding of the Easter date in both main traditions is that while the verbal definition includes terms "equinox" and "full moon" neither is any longer a true Astronomical "equinox" or "full moon" , though either may sometime coincide with the real event. This also causes additional discrepancy between Julian and Gregorian dates because Catholic and Orthodox Churches chose different non-astronomical methods to determine the equinox and the full moon.
