Easter should be the same Sunday every year, the Archbishop of Canterbury has said.
Unlike other Christian holidays such as Christmas, the dates for Easter are not always the same from one year to the next.
Speaking after the meeting of Anglican primates in Canterbury, the Most Rev Justin Welby said he would "love" to see Easter become a fixed date by the time he retires.
But he added that it might up to a decade to happen.
"School holidays and so on are all fixed 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", Mr Welby added.
Next year, Easter Sunday will fall on April 16, and in 2018 it will be on April 1.
