I want to know the answer to the following question:
When was Easter Sunday celebrated after the equinox?
All the background I'm provided with is that "By the 10th century all churches (except some on the eastern border of the Byzantine Empire) had adopted the Alexandrian Easter, which still placed the vernal equinox on 21 March, although Bede had already noted its drift in 725—it had drifted even further by the 16th century.". Is that enough to answer the question?
Answer: no
