Jigjag, Easter Island may be the ideal place for you to start your new life. I don't think quinoa and freekeh have reached there yet. There's also no problem, ambiguity with terminology - you can have Easter Saturday, Easter Sunday and Easter Monday all year round
Grunger, I'm afraid you'll just have to take your chances with the weather for the new, streamlined Easter holiday.
I am ignorant (not woefully, but actually quite happily) when it comes to some of these religious dates. The Church of Scotland never mentioned Pentecost and Whitsun/Whitsunday/Whitsuntide when I was a child. I had a quick look online and I think it must be quite tiring to keep track of all these 'significant' dates.
