Apparently about 1.5 million people - 2% of the population - are likely to attend the Church of England tomorrow. To the vast majority of the country, Easter is about chocolate, not religion. (I don't much like chocolate either, but I'll make an exception for the nice bar of marzipan chocolate waiting downstairs :-) ) So why are we still stuck with this archaic restriction? The same applies to Christmas Day, but one can at least make the argument that Christmas is a cultural celebration where people are very likely to want to spend all day at home with their families. I don't think the same is true of Easter; it's just another bank holiday weekend.
The current Easter arrangements cause other problems too. The continually moving date is disruptive for school and university terms which can't run to a standard pattern, and the earlier it falls the less likely it is to be nice weather. The Easter Act would solve that but still hasn't been brought into force.
I didn't write this post just to be an advert, but if you agree and would like this to be fixed, along with rather more major issues like faith schools and bishops in the House of Lords, join the National Secular Society or the British Humanist Association so that your opinion is heard.
EDIT: I realised my figures for church attendance above are just based on the CofE - originally this post said that they were for church in general. I can't find any good stats on total Easter church attendance, but I found these statistics on general church attendance, taking the very rough-and-ready approach of extrapolating from them gives about 5.2 million - 7% of the population.
