Is it okay if I want to move my wedding date?
Why would you want to move your wedding date?
I want to move it because I don't like the current date to be so close to a national holiday anymore.
Its your wedding, you decide when to have it but others had been counting on it to be at the first date you chose. If you change it they might get upset and then not want to go at all. I would try to leave it unless it is a dire emergency as in a matter of life or death.
You aren't helping and my future husband doesn't care about the date.
Your wedding is about you and your husband so you both should converse about it and come to an agreement. If you care about others attending, it would be wise to carefully consider how far out to move the date.
