I want to know the answer to the following question:
How did the Gregorian calendar set these same of the full moon not preceding Easterconditions?
All the background I'm provided with is that "As the rule was that the full moon preceding Easter was not to precede the equinox the equinox was fixed at 21 March for computational purposes and the earliest date for Easter was fixed at 22 March.". Is that enough to answer the question?
Answer: no
