So I have 5 days left until my wedding and it has been suggested to me by my Father that I change the time of my wedding due to the weather. We are having an outside wedding in my Father's backyard at 7pm and it has been suggested that I move it to 6pm or 5pm because it has become quite chilly. We figured the time would be fine when we sent out our invites because in the past few years it has been really warm up until the end of October but weather is unpredictable and now it will be in the low 60s to high 50s on Saturday night. It's a small wedding, about 50 people, it is in my Father's backyard so a time change wouldn't be a problem for the venue and I wouldn't have a problem with vendors because most of my friends and family are in the wedding business so they no problem with the time change. The only problem I have is the guests. So my question is, is too late to change the time? I'm sure we can get a hold of all of them I'm just worried about it being rude.
