When I was a child I looked forward to Easter, not for religion, although I did understand about Christianity, but because of the Easter eggs we used to get (I was a child, forgive me).
As I got older I realised that Easter wasn’t on a set day, like the 25 December for Christmas. But it seems to be that it has to run Friday Saturday and Sunday and is linked somehow to the Jewish Calendar? But also to the phases of the moon, so Easter drifts a slowly, then jumps around. Any time between late March and April if I remember. It used to make the Easter break at school a bit odd too. If anyone knows the correct reasons let me know?
