I have heard many diferent explinations for how long until there will be anotehr resouce change on the servers, I've heard every3 days, I've heard every Saturday. So far, I don't believe any have been accurate. Is the resource shift just random or is there actually some logic to it.

Just trying to save the time from running to all my harvestors and making sure that they are still on.

Maybe they should put an in game e-mail that tells you your harvestor has stopped...
