It has been announced that the Scottish Episcopal Church will begin moving over to the new method for calculating the date of Easter from April 2012. After this time, the date will be calculated according to a new algorithm which is aligned with modern astronomical measurements rather than the older means of calculation which has become out of date.
Concerns had been expressed that the new method would mean that the Scottish Episcopal Church would always keep Easter on a different date to the Church of England. This has been resolved by using the New Revised Algorithm which will mean that Easter will be kept on the same day as the Church of England on alternate years. On other years, the date of Easter will be aligned with the Episcopal Church in the USA.
It is expected that some congregations will remain with the old method of calculation for a few years. The College of Bishops has indicated that it will issue a moratorium against the use of the old algorithm and the old calendar on 1 April 2020.
