I've been following with interest the conversation between Christian leaders about fixing the date of Easter to a particular day in the calendar—like the second or third Sunday in April. Back in January, Justin Welby, the Archbishop of Canterbury, voiced his support for the idea, joining leaders of the Catholic, Orthodox, and Coptic churches. Welby was even so bold as to suggest that the date of Easter could be fixed in as few as five or ten years, saying, "School holidays and so on are all fixed—it affects almost everything you do in the spring and summer. I would love to see it before I retire."
