Most JWs have no idea at all how the "Church Year" works.
They think that the church hasn't sussed out that the anniversay of Jesus' death couldn't always fall on a Friday
They totally fail to realise that that these sort of structures and frameworks are out of CHOICE not IGNORANCE.
It's just a different way of observing.
So they feel that the "Recommended Memorial Bible Readings" that they have for memorial week are some exclusive fab idea they've had! But they are totally ignorant of the mass of "Lent courses" and "Study programmes" available culminating in reflections on Good Friday and celebrations on Easter Sunday.
Far more importance and significance is given to Jesus death and ressurection in "Christendom" than in any Kingdom hall.
I've said this before, but Christianity completely wiped out pagan significance of dates by hijacking them and giving Jesus the attention.
Who do you think would be most annoyed. God for the honor given on previously "pagan dates" or Satan, the one supposedly behind those pagan festivals who just lost all his publicity?
