Change the Date Etiquette

So we are postponing to next November and I am planning to contact our guests and let them know. I also want to send out “change the date” cards, but I’m not sure when to do this. We have the new date set, so do I send them in the next few weeks (when we would have been sending invitations) or wait until next spring when save the dates would normally go out?


Also, we are still planning on getting married on our original date in a very small ceremony with just our parents. For those of you that did this, but still are planning to have a full ceremony and reception at a later date with all your guests, did you tell them you’re already married? I don’t feel the need to formally announce it, but don’t want some people to know and others not because someone if bound to get offended. But I also don’t want to keep it a secret for a year...
